How bacteria keep proteins moving

Proteins keep Cdc55 in its place

Proteins keep Cdc55 in its place R ossio and Yoshida reveal how cells control the location of the mitosis-regulating protein Cdc55. Cdc55 is a key component of the protein phosphatase 2A (PP2A) complex, which helps determine when cells begin and end mitosis. Two other proteins, Zds1 and Zds2, keep the complex under control. They switch on PP2A to nudge the cell into mitosis and switch it off to...

Special Rumen Microbiology

Bacteria make up about half of the living organisms inside of the rumen. However, they do more than half of the work in the rumen. The bacteria work together. Some breakdown certain carbohydrates and proteins which are then used by others. Some require certain growth factors, such as B-vitamins, which are made by others. Some bacteria help to clean up the rumen of others’ end products, such as ...

Two Proteins from Snake Venom have Potent Antibacterial Effects against Bacillus anthracis and Streptococcus pneumoniae

Background: Antibacterial proteins are widely expressed in snake venoms. Previously, we have isolated two immunodominant proteins with molecular weights of 14 and 65kD from the snake venom of Naja naja oxiana (N. oxiana). It was demonstrated that they had potent inhibitory effects against gram-positive bacteria, S. aureus and B. subtilis but were less effective against gram-negative bacteria, s...
