Protein
Lipopolysaccharide core heptose(I) kinase RfaP
Organism
Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
Function
Catalyzes the phosphorylation of heptose(I) of the outer membrane lipopolysaccharide core. The phosphorylation of the lipopolysaccharide core seems to occur prior to translocation to the periplasm and attachment of O-antigen. Also has protein-tyrosine kinase activity: autophosphorylates on all Tyr residues; in vitro can phosphorylate poly(Glu,Tyr).
Similarity
Belongs to the protein kinase superfamily. KdkA/RfaP family.
