Regulation of sialic acid metabolism in Escherichia coli: role of N-acylneuraminate pyruvate-lyase.

abstract：:Caulobacter crescentus cells adhere to surfaces by using an extremely strong polar adhesin called the holdfast. The polysaccharide component of the holdfast is comprised in part of oligomers of N-acetylglucosamine.
