CC -!- FUNCTION: Required for the first step of diphthamide biosynthesis, a
CC post-translational modification of histidine which occurs in elongation
CC factor 2. DPH1 and DPH2 transfer a 3-amino-3-carboxypropyl (ACP) group
CC from S-adenosyl-L-methionine (SAM) to a histidine residue, the reaction
CC is assisted by a reduction system comprising KTI11/DPH3 and a NADH-
CC dependent reductase, predominantly CBR1. Acts as an electron donor to
CC reduce the Fe-S cluster in DPH1-DPH2 keeping the [4Fe-4S] clusters in
CC the active and reduced state. Restores iron to DPH1-DPH2 iron-sulfur
CC clusters which have degraded from [4Fe-4S] to [3Fe-4S] by donating an
CC iron atom to reform [4Fe-4S] clusters, in a manner dependent on the
CC presence of elongation factor 2 and SAM. Associates with the elongator
CC complex and is required for tRNA Wobble base modifications mediated by
CC the elongator complex. The elongator complex is required for multiple
CC tRNA modifications, including mcm5U (5-methoxycarbonylmethyl uridine),
CC mcm5s 2U (5-methoxycarbonylmethyl-2-thiouridine), and ncm5U (5-
CC carbamoylmethyl uridine). {ECO:0000250|UniProtKB:Q3E840}.

CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000250|UniProtKB:Q3E840};
CC -!- PATHWAY: Protein modification; peptidyl-diphthamide biosynthesis.
CC {ECO:0000250|UniProtKB:Q3E840}.
CC -!- SUBUNIT: Component of the 2-(3-amino-3-carboxypropyl)histidine synthase
CC complex composed of DPH1, DPH2, DPH3 and a NADH-dependent reductase,
CC predominantly CBR1. {ECO:0000250|UniProtKB:Q3E840}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC -!- DOMAIN: The DPH-type metal-binding (MB) domain can also bind zinc.
CC However, iron is the physiological binding partner as zinc binding
CC impairs the protein electron donor function.
CC {ECO:0000250|UniProtKB:Q3E840}.
CC -!- SIMILARITY: Belongs to the DPH3 family. {ECO:0000305}.
