yclQ

Gene
yclQ
Protein
Petrobactin-binding protein YclQ
Organism
Bacillus subtilis (strain 168)
Length
317 amino acids
Function
Part of the ABC transporter complex YclNOPQ involved in uptake of ferric-petrobactin. Petrobactin is a photoreactive 3,4-catecholate siderophore produced by many members of the B.cereus group, including B.anthracis. Binds selectively iron-free and ferric petrobactin and the petrobactin precursor 3,4-dihydroxybenzoic acid (3,4-DHB).
Similarity
Belongs to the bacterial solute-binding protein 8 family.
Mass
34.792 kDa
