Organism

Bacillus subtilis [Complete proteome] [HAMAP]

Taxonomic identifier

1423 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Bacillales › Bacillaceae › Bacillus

Protein attributes

Sequence length	496 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Autolysins are involved in some important biological processes such as cell separation, cell-wall turnover, competence for genetic transformation, formation of the flagella - in particular of its basal body - and sporulation. Has a high affinity for teichoic acid-endowed peptidoglycan.
Catalytic activity	Hydrolyzes the link between N-acetylmuramoyl residues and L-amino acid residues in certain cell-wall glycopeptides.
Subcellular location	Secreted › cell wall.
Induction	Under control of sigD. Ref.4
Disruption phenotype	Cells lacking this gene show no motility changes on swarm plates; however in combination with a acetylglucosaminidase deletion (lytD, AC P39848) greatly reduced motility is seen. Ref.5
Sequence similarities	Belongs to the N-acetylmuramoyl-L-alanine amidase 3 family.
