CC -!- FUNCTION: NADH-dependent reductase for DPH3 and cytochrome b5. Required
CC for the first step of diphthamide biosynthesis, a post-translational
CC modification of histidine which occurs in elongation factor 2. DPH1 and
CC DPH2 transfer a 3-amino-3-carboxypropyl (ACP) group from S-adenosyl-L-
CC methionine (SAM) to a histidine residue, the reaction is assisted by a
CC reduction system comprising DPH3 and a NADH-dependent reductase,
CC predominantly CBR1. By reducing DPH3, also involved in the formation of
CC the tRNA wobble base modification mcm5s 2U (5-methoxycarbonylmethyl-2-
CC thiouridine), mediated by the elongator complex. The cytochrome b5/NADH
CC cytochrome b5 reductase electron transfer system supports the catalytic
CC activity of several sterol biosynthetic enzymes.
