Modern DNA sequencing capabilities have led to the discovery of a large number of new bacteriophage genomes, which are a rich source of novel proteins with an unidentified biological role. The genome of Enterobacter cancerogenus bacteriophage Enc34 contains several proteins of unknown function that are nevertheless conserved among distantly related phages. Here, we report the crystal structure of a conserved Enc34 replication protein ORF6 which contains a domain of unknown function DUF2815. Despite the low (~15%) sequence identity, the Enc34 ORF6 structurally resembles the gene 2...

Cultivable microbiota presents in a coffee semi-dry processing wastewater treatment plant (WTP) was identified. Thirty-two operational taxonomic units (OTUs) were detected, these being 16 bacteria, 11 yeasts and 4 filamentous fungi. Bacteria dominated the microbial population (11.61 log CFU mL(- 1)), and presented the highest total diversity index when observed in the WTP aerobic stage (Shannon = 1.94 and Simpson = 0.81). The most frequent bacterial species were Enterobacter asburiae, Sphingobacterium griseoflavum, Chryseobacterium bovis, Serratia marcescens, Corynebacterium flavescens, Acetobacter orientalis and Acetobacter indonesiensis; these showed the largest total bacteria populations in the WTP, with approximately 10 log CFU mL(- 1)...
