Polysaccharide chain length determinant N-terminal domain (IPR003856)

Short name: LPS_length_determ_N_term

Overlapping homologous superfamilies


Domain relationships



A number of related proteins are involved in the synthesis of lipopolysaccharide, O-antigen polysaccharide, capsule polysaccharide and exopolysaccharides. Chain length determinant protein (or wzz protein) is involved in lipopolysaccharide (lps) biosynthesis, conferring a modal distribution of chain length on the O-antigen component of lps [PMID: 9573151]. It gives rise to a reduced number of short chain molecules and increases in numbers of longer molecules, with a modal value of 20. The MPA/MPA2 proteins function in CPS and EPS polymerisation and export [PMID: 10658645].
