| STM4433 | nanM | STM4433 | STM1130 | Putative thiamine pyrophosphate-requiring enzyme; Oxidoreductase family; similar to E. coli putative virulence factor (AAC74152.1); Blastp hit to AAC74152.1 (307 aa), 29% identity in aa 1 - 188, 52% identity in aa 272 - 296. | Putative inner membrane protein; Converts alpha-N-acetylneuranimic acid (Neu5Ac) to the beta- anomer, accelerating the equilibrium between the alpha- and beta- anomers. Probably facilitates sialidase-negative bacteria to compete sucessfully for limited amounts of extracellular Neu5Ac, which is likely taken up in the beta-anomer. In addition, the rapid removal of sialic acid from solution might be advantageous to the bacterium to damp down host responses; Belongs to the NanM family. | 0.584 |
