GN Name=lspA; Synonyms=lsp; OS Enterobacter aerogenes (Aerobacter aerogenes). OC Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacteriales; OC Enterobacteriaceae; Enterobacter. OX NCBI_TaxID=548; RN [1] RP NUCLEOTIDE SEQUENCE. RC STRAIN=ATCC 13048; RX MEDLINE=90094256; PubMed=2403548; RA Isaki L., Kawakami M., Beers R., Hom R., Wu H.C.; RT "Cloning and nucleotide sequence of the Enterobacter aerogenes signal RT peptidase II (lsp) gene."; RL J. Bacteriol. 172:469-472(1990). CC -!- FUNCTION: This protein specifically catalyzes the removal of CC signal peptides from prolipoproteins. CC -!- CATALYTIC ACTIVITY: Release of signal peptides from bacterial CC membrane prolipoproteins. Hydrolyzes -Xaa-Yaa-Zaa-|- CC (S,diacylglyceryl)Cys-, in which Xaa is hydrophobic (preferably CC Leu), and Yaa (Ala or Ser) and Zaa (Gly or Ala) have small, CC neutral side chains. CC -!- PATHWAY: Lipoprotein biosynthesis; second step. CC -!- SUBCELLULAR LOCATION: Integral membrane protein. Inner membrane CC (By similarity). CC -!- SIMILARITY: Belongs to the peptidase A8 family. CC -------------------------------------------------------------------------- CC This Swiss-Prot entry is copyright.
