Phenotypes of a mutant

• a ''[gene|4F9D70C4BB4FCA809BEAC341C3F8122FB7FD8872|cwlO] [gene|321F248C22D7283C0F3323F1F4069E36F8D7FE6C|lytE]'' mutant is not viable [Pubmed|17581128,22139507]
• shorter, fatter cells, this can be rescued by addition of Mg(2+) [Pubmed|23869552,23855774]

The protein

Catalyzed reaction/ biological activity

• cleaves the peptide bond between D-Glu (position 2 in the peptioglycan peptide) and m-diamino pimelic acid (position 3) [Pubmed|18266855]

Protein family

• peptidase C40 family (according to Swiss-Prot)

Paralogous protein(s)

• the C-terminal D,L-endopeptidase domains of [protein|321F248C22D7283C0F3323F1F4069E36F8D7FE6C|LytE], [protein|E8B88CBE4F9121DFEEF099D7947CD1E1AE656160|LytF], [protein|0FBE3F7ECACA7FCFAA4EE32E9B2BB35F0B793C0F|CwlS], and [protein|4F9D70C4BB4FCA809BEAC341C3F8122FB7FD8872|CwlO] exhibit strong sequence similarity
