family of mostly uncharacterized proteins similar to B.subtilis YvcK
One member of this protein family, YvcK from Bacillus subtilis, has been proposed to play a role in carbon metabolism, since its function is essential for growth on intermediates of the Krebs cycle and the pentose phosphate pathway. In general, this family of mostly uncharacterized proteins is related to the CofD-like protein family. CofD has been characterized as a 2-phospho-L-lactate transferase involved in F420 biosynthesis. This family appears to have the same conserved phosphate binding site as the other family in this hierarchy, but a different substrate binding site.
