Bifunctional autolysin precursor, putative; Endohydrolysis of the di-N-acetylchitobiosyl unit in high- mannose glycopeptides and glycoproteins containing the -[(Man)5(GlcNAc)2]-Asn structure. One N-acetyl-D-glucosamine residue remains attached to the protein; the rest of the oligosaccharide is released intact. Cleaves the peptidoglycan connecting the daughter cells at the end of the cell division cycle, resulting in the separation of the two newly divided cells. Acts as an autolysin in penicillin-induced lysis (By similarity); In the C-terminal section; belongs to the glycosyl hydrolas [...]

Conserved hypothetical protein; Catalyzes the transfer of a lysyl group from L-lysyl- tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), a major component of the bacterial membrane with a positive net charge. LPG synthesis contributes to bacterial virulence as it is involved in the resistance mechanism against cationic antimicrobial peptides (CAMP) produces by the host's immune system (defensins, cathelicidins) and by the competing microorganisms (bacteriocins). In fact, the modification of anionic phosphatidylglycerol with positively [...]

Autolysin; Has weak lytic activity toward S.aureus cells. Belongs to the N-acetylmuramoyl-L-alanine amidase 2 family.

Bifunctional autolysin precursor.

Cysteine protease precursor, putative; Cysteine protease that plays an important role in the inhibition of host innate immune response. Degrades host elastin, fibrogen, fibronectin and kininogen. Blocks phagocytosis of opsonised S. aureus by neutrophils and monocytes by inducing their death in a proteolytic activity-dependent manner. Decreases surface expression of the 'don't eat me' signal CD31 on neutrophils. Cleaves host galectin- 3/LGALS3, thereby inhibiting the neutrophil-activating ability of the lectin.

Glutamyl endopeptidase precursor, putative; Preferentially cleaves peptide bonds on the carboxyl-terminal side of aspartate and glutamate. Along with other extracellular proteases it is involved in colonization and infection of human tissues. Required for proteolytic maturation of thiol protease SspB and inactivation of SspC, an inhibitor of SspB. It is the most important protease for degradation of fibronectin-binding protein (FnBP) and surface protein A, which are involved in adherence to host cells. May also protect bacteria against host defense mechanism by cleaving the immunoglobu [...]

Autolysin precursor, putative; Peptidoglycan hydrolase involved in the splitting of the septum during cell division. Binds to both alpha and beta-chains of human fibrinogen as well as fibronectin, which suggests a role in the colonization of host factor-coated material or host tissue. Also exhibits lytic activity against S.carnosus and S.aureus cells but not against M.luteus cells.

Conserved hypothetical protein.

Conserved hypothetical protein; Participates in chromosomal partition during cell division. May act via the formation of a condensin-like complex containing Smc and ScpB that pull DNA away from mid-cell into both cell halves.
