For the first time ...
In biology, autolysis, more commonly known as self-digestion, refers to the destruction of a cell through the action of its own enzymes. It may also refer to the digestion of an enzyme by another molecule of the same enzyme. The term derives from the Greek αὐτο- ("self") and λύσις ("splitting"). Web2.7 Autolysins. Autolysins are a family of enzymes which play important roles in Gram-positive organisms, breaking down peptidoglycan and enabling turnover of the cell wall (Uehara & Bernhardt, 2011 ). An autolysin in S. suis, Atl, has been implicated in virulence and contains an N-acetylmuramoyl-L-alanine amidase domain.
WebAutolysins lyse the old peptidoglycan on the outside of the cell wall. What is transpeptidation and why is it important to both the cell and clinical medicine? Transpeptidation is the final step of peptidoglycan synthesis. It forms the peptide cross-links between muramic acid residues in adjacent glycan chains. In medicine, it is inhibited by ...
