This family represents the C-terminal region of the male sterility protein in a number of arabidopsis and drosophila. A sequence-related jojoba acyl CoA reductase is also included. [1]. 9351246. The Arabidopsis MALE STERILITY 2 protein shares similarity with. reductases in elongation/condensation complexes.. Aarts MG, Hodge R, Kalantidis K, Florack D, Wilson ZA, Mulligan.

NmrA is a negative transcriptional regulator involved in the post-translational modification of the transcription factor AreA. NmrA is part of a system controlling nitrogen metabolite repression in fungi [1]. This family only contains a few sequences as iteration results in significant matches to other Rossmann fold families. [1]. 11726498. The structure of the negative transcriptional regulator NmrA. reveals a structural superfamily which includes the short-chain. dehydrogenase/reductases..

L-rhamnose is a saccharide required for the virulence of some bacteria. Its precursor, dTDP-L-rhamnose, is synthesised by four different enzymes the final one of which is RmlD. The RmlD substrate binding domain is responsible for binding a sugar nucleotide [1,2]. [1]. 12057193. Variation on a Theme of SDR. dTDP-6-Deoxy-L- lyxo-4-Hexulose.

The enzyme 3 beta-hydroxysteroid dehydrogenase/5-ene-4-ene isomerase (3 beta-HSD) catalyses the oxidation and isomerisation of 5-ene-3 beta-hydroxypregnene and 5-ene-hydroxyandrostene steroid precursors into the corresponding 4-ene-ketosteroids necessary for the formation of all classes of steroid hormones.
