Disease relevance of Atu1136

  • Glycerol trinitrate (GTN) reductase, which enables Agrobacterium radiobacter to utilize GTN and related explosives as sources of nitrogen for growth, was purified and characterized, and its gene was cloned and sequenced [1].
  • Glycerol trinitrate reductase (NerA) from Agrobacterium radiobacter, a member of the old yellow enzyme (OYE) family of oxidoreductases, was expressed in and purified from Escherichia coli [2].

High impact information on Atu1136

  • Structure and mechanism of a bacterial haloalcohol dehalogenase: a new variation of the short-chain dehydrogenase/reductase fold without an NAD(P)H binding site [3].
  • First, we demonstrate the functional activity of these Tat systems in vivo, since expression of the tatABC operons from S.typhimurium or A.tumefaciens in an E.coli tat null mutant strain resulted in efficient Tat-dependent export of an E.coli cofactor-containing substrate, TMAO reductase [4].
  • GTN reductase and PETN reductase were very similar in many respects except in their distinct preferences for NADH and NADPH cofactors, respectively [1].
  • The reductase activity of this enzyme is precisely the reaction ascribed to its T-region-encoded homolog, Mas1, which is responsible for biosynthesis of mannopine in crown gall tumors [5].
  • Ornithine, resulting from the action of arginase on arginine, could be used as a nitrogen source via transamination to delta 1-pyrroline-5-carboxylate and reduction of the latter compound to proline by a reductase (both enzymatic activities are probably chromosomally encoded) [6].
