3-148 4.81e-72

sugar-phosphate isomerase, RpiB/LacA/LacB family; Proteins of known function in this family act as sugar (pentose and/or hexose)-phosphate isomerases, including the LacA and LacB subunits of galactose-6-phosphate isomerases from Gram-positive bacteria and RpiB. RpiB is the second ribose phosphate isomerase of E. coli. It lacks homology to RpiA, its inducer is unknown (but is not ribose), and it can be replaced by the homologous galactose-6-phosphate isomerase of Streptococcus mutans, all of which suggests that the ribose phosphate isomerase activity of RpiB is a secondary function. On the other hand, there appear to be a significant number of species which contain rpiB, lack rpiA and seem to require rpi activity in order to complete the pentose phosphate pathway.

ribose 5-phosphate isomerase; This family is a member of the RpiB/LacA/LacB subfamily (TIGR00689) but lies outside the RpiB equivalog (TIGR01120) which is also a member of that subfamily. Ribose 5-phosphate isomerase is an essential enzyme of the pentose phosphate pathway; a pathway that appears to be present in the actinobacteria. The only candidates for ribose 5-phosphate isomerase in the Actinobacteria are members of this family.
