Abstract
Poly-alpha-2,8 N-acetylneuraminic acid (polySia) is an important virulence factor in infections caused by Escherichia coli K1 and Neisseria meningitidis B. In E. coli K1 a membranous CMP-NeuAc: poly-alpha-2,8 sialosyl sialyltransferase (polysialyltransferase) complex catalyses the synthesis of linear polySia chains. The complex also elongates sialyl oligomers that serve as exogenous acceptors. The gene encoding a polysialyltransferase of E. coli has been identified by subcloning and DNA sequence analysis. The subcloned DNA fragment codes for a polypeptide with a molecular mass of 47 kDa catalysing the in vitro synthesis of polySia by elongation of exogenous acceptors.Entities:
