The ins and outs of Bacillus proteases: activities, functions and commercial significance

Because the majority of bacterial species divide by binary fission, and do not have distinguishable somatic and germline cells, they could be considered to be immortal. However, bacteria 'age' due to damage to vital cell components such as DNA and proteins. DNA damage can often be repaired using efficient DNA repair mechanisms. However, many proteins have a functional 'shelf life'; some are short lived, while others are relatively stable....
