The apo structure of a bacterial aldo-keto reductase AKR14A1
Template:ABSTRACT PUBMED 23103600
Function
[GPR_ECOLI] Catalyzes the stereospecific, NADPH-dependent reduction of L-glyceraldehyde 3-phosphate (L-GAP). The physiological role of gpr is the detoxification of L-GAP, which may be formed by non-enzymatic racemization of GAP. Also involved in the stress response as a methylglyoxal reductase which converts the toxic metabolite methylglyoxal to acetol in vitro and in vivo.[1] [2] [3]
About this Structure
4ast is a 8 chain structure with sequence from Ecobd. Full crystallographic information is available from OCA.
