9.B.331. The ATP Binding Protein (ATP-BP) Family
These proteins are annotated as either ATP binding proteins or ATPases in the NCBI protein database. The three proteins numbered 9.B.331.1.1, 1.2 and 1.3 map adjacent to each other, adjacent to a MOP superfamily protein of TC# 2.A.66.12.6, and also adjacent (on the other side) to a disulfide oxidoreductase and a hydrogenase. These three proteins may have an internal triplication based on hydrophathy profiles. TC Blast searches suggest they may have limited sequence similarity for motifs also found in the ATPases of various ABC transporters.
Putative ATPase, YghR, of 252 aas with three apparent internal repeats, each with two low peaks of hydrophobicity, the first showing greater hydrophobicity than the second.
YghR of E. coli
YghS of 237 aas and an apparent internal triplication like TC# 9.B.331.1.1. The three homologous proteins, 9.B.331.1.1, 1.2 and 1.3, are encoded by adjacent genes that are also adjacent to a MOP superfamily protein, TC# 2.A.66.12.6.
YghS of E. coli
YghT of 234 aas and three apparent internal repeats.
YghT of E. coli
Uncharacterized protein of 514 aas.
