AlcB

Siderophore biosynthesis protein domain
AlcB
SMART accession number:SM01006
Description: AlcB is the conserved 45 residue region of one of the proteins of a complex which mediates alcaligin biosynthesis in Bordetella and aerobactin biosynthesis in E. coli and other bacteria. The protein appears to catalyse N-acylation of the hydroxylamine group in N-hydroxyputrescine with succinyl CoA - an activated mono-thioester derivative of succinic acid that is an intermediate in the Krebs cycle.
Interpro abstract (IPR019432):

This entry represents a conserved 45 residue region found in one of the proteins from a siderophore biosynthesis complex [(PUBMED:9266668)]. The siderophore produced by this complex varies with species, e.g. alcaligin is produced in Bordetella, aerobactin in Escherichia coli and mycobactin in mycobacteria. The protein appears to catalyse N-acylation of the hydroxylamine group in N-hydroxyputrescine with succinyl CoA - an activated mono-thioester derivative of succinic acid that is an intermediate in the Krebs cycle [(PUBMED:15719346)].
