    Functioni

    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).1 Publication

    Catalytic activityi

    ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
