Phytocystatins are cysteine proteinase inhibitors present in plants. They play crucial role in maintaining protease-anti protease balance and are involved in various endogenous processes. Thus, they are suitable and convenient targets for genetic engineering which makes their isolation and characterisation from different sources the need of the hour. In the present study a phytocystatin has been isolated from garlic (Allium sativum) by a simple two-step process using ammonium sulphate fractionation and gel filtration chromatography on Sephacryl S-100HR with a fold purification of 152...

INTRODUCTION: Systemic enzyme therapy can play an important role in maintaining normal inflammatory processes within the body and thereby helps support and speed up healing. In the course of the anti-inflammatory action, enzymes degrade damaged cells and necrotic material and, through the inactivation of mediators and toxic products, they restrict the edema and pain. METHOD: The study conducted at Grant Medical College, Mumbai, India was a clinical trial comparing the efficacy and tolerability of three oral enzyme treatment groups-oral tablets containing trypsin:chymotrypsin (TC) (Chymoral Forte(®)), serratiopeptidase (S) 5 mg oral tablets, and oral enzyme tablets containing trypsin 48 mg, bromelain 90 mg, and rutoside 100 mg (TBR)-to evaluate their healing potential in surgical wounds after orthopedic surgery...

Expression of proteases in heterologous hosts remains an ambitious challenge due to severe problems associated with digestion of host proteins. On the other hand, proteases are broadly used in industrial applications and resemble promising drug candidates. Bromelain is an herbal drug that is medicinally used for treatment of oedematous swellings and inflammatory conditions and consists in large part of proteolytic enzymes. Even though various experiments underline the requirement of active cysteine proteases for biological activity, so far no investigation succeeded to clearly clarify the pharmacological mode of action of bromelain...

Bromelain is a mixture of proteolytic enzymes found in pineapple (Ananas comosus) plants. Bromelain can be found in several parts of the pineapple plant, including the stem, fruit, leaves and peels. High demand from bromelain has resulted in gradual increases in bromelain production. Such increases in production have led to the need for a bromelain production strategy that yields more purified bromelain at a lower cost and with fewer productions steps. Previously, bromelain was purified using conventional centrifugation, ultrafiltration and lyophilisation...
