aminotransferase, LLPSF_NHT_00031 family This clade of aminotransferases is a member of the pfam01041 (DegT/DnrJ/EryC1/StrS) superfamily. The family is named after the instance in Leptospira interrogans serovar Lai, str. 56601, where it is the 31st gene in the 91-gene lipopolysaccharide biosynthesis locus. Members of this family are generally found within a subcluster of seven or more genes including an epimerase/dehydratase, four genes homologous to the elements of the neuraminic (sialic) acid biosynthesis cluster (NeuABCD) and a nucleotidyl transferase. Together it is very likely that these enzymes direct the biosynthesis of a nine-carbon sugar analogous to CMP-neuraminic acid. These seven genes form the core of the cassette, although they are often accompanied by additional genes that may further modify the product sugar. |
