Structural highlights
FunctionSQUU_ECOLI Reduces 3-sulfolactaldehyde (SLA) to 2,3-dihydroxypropane 1-sulfonate (DHPS) (PubMed:24463506, Ref.6). Metabolite profiling studies showed that the enzyme also catalyzes in vitro the NADH-dependent reduction of succinic semialdehyde (SSA) to 4-hydroxybutyrate (GHB), and that it could be involved in the metabolism of SSA, and other potentially toxic intermediates that may accumulate under stress conditions (PubMed:19372223). However, the enzyme exhibits a 42,000-fold greater catalytic efficiency for the reduction of SLA over SSA (Ref.6). Shows no detectable activity on the analogous glycolytic intermediate glyceraldehyde-3-phosphate (Ref.6).[1] [2] [3] References
