Abstract excerpt
A mutation in galU that causes the lack of O34-antigen lipopolysaccharide (LPS) in Aeromonas hydrophila strain AH-3 was identified. It was proved that A. hydrophila GalU is a UDP-glucose pyrophosphorylase responsible for synthesis of UDP-glucose from glucose 1-phosphate and UTP. The galU mutant from this strain showed two types of LPS structures, represented by two bands on LPS gels. The first one (slow-migrating...
