Enzymes, representing the largest and by far most complex group of proteins, play an essential role in all processes of life, including metabolism, gene expression, cell division, the immune system, and others. Their function, also connected to most diseases or stress control makes them interesting targets for research and applications in biotechnology, medical treatments, or diagnosis. Their functional parameters and other properties are collected, integrated, and made available to the scientific community in the BRaunschweig ENzyme DAtabase (BRENDA)...

Heterologous expression of high amounts of recombinant proteins is a milestone for research and industrial purposes. Single domain antibodies (sdAbs) are heavy-chain only antibody fragments with applications in the biotechnological, medical and industrial fields. The simple nature and small size of sdAbs allows for efficient expression of the soluble molecule in different hosts. However, in some cases, it results in low functional protein yield. To overcome this limitation, expression of a 6xHistag sdAb was attempted in different conditions in Escherichia coli BL21(DE3) cells...

REVIEW
Joshua A Jackman, Abdul Rahim Ferhan, Nam-Joon Cho
In recent years, nanoplasmonic sensors have become widely used for the label-free detection of biomolecules across medical, biotechnology, and environmental science applications. To date, many nanoplasmonic sensing strategies have been developed with outstanding measurement capabilities, enabling detection down to the single-molecule level. One of the most promising directions has been surface-based nanoplasmonic sensors, and the potential of such technologies is still emerging. Going beyond detection, surface-based nanoplasmonic sensors open the door to enhanced, quantitative measurement capabilities across the biointerfacial sciences by taking advantage of high surface sensitivity that pairs well with the size of medically important biomacromolecules and biological particulates such as viruses and exosomes...

Lactococcus lactis has progressed a long way since its discovery and initial use in dairy product fermentation, to its present biotechnological applications in genetic engineering for the production of various recombinant proteins and metabolites that transcends the heterologous species barrier. Key desirable features of this gram-positive lactic acid non-colonizing gut bacteria include its generally recognized as safe (GRAS) status, probiotic properties, the absence of inclusion bodies and endotoxins, surface display and extracellular secretion technology, and a diverse selection of cloning and inducible expression vectors...

Microalgae, also called microphytes, are a vast group of microscopic photosynthetic organisms living in aquatic ecosystems. Microalgae have attracted the attention of biotechnology industry as a platform for extracting natural products with high commercial value. During last decades, microalgae have been also used as cost-effective and easily scalable platform for the production of recombinant proteins with medical and industrial applications. Most progress in this field has been made with Chlamydomonas reinhardtii as a model organism mainly because of its simple life cycle, well-established genetics and ease of cultivation...

The production of natural aroma compounds is an expanding field within the branch of white biotechnology. Three aromatic compounds of interest are cinnamaldehyde, the typical cinnamon aroma that has applications in agriculture and medical sciences, as well as cinnamyl alcohol and hydrocinnamyl alcohol, which have applications in the cosmetic industry. Current production methods, which rely on extraction from plant materials or chemical synthesis, are associated with drawbacks regarding scalability, production time, and environmental impact...

Global demand for biotechnological products has increased steadily over the years. Thus, need for optimized processes and reduced costs appear as a key factor in the success of this market. A process tool of high importance is the direct or indirect use of enzymes to catalyze the generation of various substances. Also, obtaining aromas and pigments from natural sources has becoming priority in cosmetic and food industries in order to supply the demand from consumers to substitute synthetic compounds, especially when by-products can be used as starting material for this purpose...

Laccase belongs to a small group of enzymes called the blue multicopper oxidases, having the potential ability of oxidation. It belongs to enzymes, which have innate properties of reactive radical production, but its utilization in many fields has been ignored because of its unavailability in the commercial field. There are diverse sources of laccase producing organisms like bacteria, fungi and plants. In fungi, laccase is present in Ascomycetes, Deuteromycetes, Basidiomycetes and is particularly abundant in many white-rot fungi that degrade lignin...

Fungi are important natural product sources that have enormous potential for the production of novel compounds for use in pharmacology, agricultural applications and industry. Compared with other natural sources such as plants, fungi are highly diverse but understudied. However, research on Cladosporium cladosporioides revealed the existence of bioactive products such as p-methylbenzoic acid, ergosterol peroxide (EP) and calphostin C as well as enzymes including pectin methylesterase (PME), polygalacturonase (PG) and chlorpyrifos hydrolase...

The metabolic status of individual cells in microbial cultures can differ, being relevant for biotechnology, environmental and medical microbiology. However, it is hardly understood in molecular detail due to limitations of current analytical tools. Here, we demonstrate that FACS in combination with proteomics can be used to sort and analyze cell populations based on their metabolic state. A previously established GFP reporter system was used to detect and sort single Corynebacterium glutamicum cells based on the concentration of branched chain amino acids (BCAA) using FACS...

Immunoglobulin Y (IgY) is central to our understanding of immunoglobulin evolution. It has links to antibodies from the ancestral IgM to the mucosal IgX and IgA, as well as to mammalian serum IgG and IgE. IgY is found in amphibians, birds and reptiles, and as their most abundant serum antibody, is orthologous to mammalian IgG. However, IgY has the same domain architecture as IgM and IgE, lacking a hinge region and comprising four heavy-chain constant domains. The relationship between IgY and the mucosal antibodies IgX and IgA is discussed herein, in particular the question of how IgA could have contributed to the emergence of IgY...

Glycosaminoglycans, such as hyaluronic acid and chondroitin sulphate, are not only more and more required as main ingredients in cosmeceutical and nutraceutical preparations, but also as active principles in medical devices and pharmaceutical products. However, while biotechnological production of hyaluronic acid is industrially established through fermentation of Streptococcus spp. and recently Bacillus subtilis, biotechnological chondroitin is not yet on the market.

Horseradish peroxidase (HRP) is used in various biotechnological and medical applications. Since its isolation from plant provides several disadvantages, the bacterium Escherichia coli was tested as recombinant expression host in former studies. However, neither production from refolded inclusion bodies nor active enzyme expression in the periplasm exceeded final titres of 10mg per litre cultivation broth. Thus, the traditional way of production of HRP from plant still prevails. In this study, we revisited the recombinant production of HRP in E...

BACKGROUND: Gallbladder cancer is highly lethal, with notable differences in incidence by geography and ethnic background. The aim of this study was to identify common genetic susceptibility alleles for gallbladder cancer. METHODS: In this case-control genome-wide association study (GWAS), we did a genome-wide scan of gallbladder cancer cases and hospital visitor controls, both of Indian descent, followed by imputation across the genome. Cases were patients aged 20-80 years with microscopically confirmed primary gallbladder cancer diagnosed or treated at Tata Memorial Hospital, Mumbai, India, and enrolled in the study between Sept 12, 2010, and June 8, 2015...
