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 dph3 and a NADH-dependent
CC       reductase, predominantly cbr1. Acts as an electron donor to reduce the
CC       Fe-S cluster in dph1-dph2 keeping the [4Fe-4S] clusters in the active
CC       and reduced state. Restores iron to dph1-dph2 iron-sulfur clusters
CC       which have degraded from [4Fe-4S] to [3Fe-4S] by donating an iron atom
CC       to reform [4Fe-4S] clusters, in a manner dependent on the presence of
CC       elongation factor 2 and SAM. Associates with the elongator complex and
CC       is required for tRNA Wobble base modifications mediated by the
CC       elongator complex. The elongator complex is required for multiple tRNA
CC       modifications, including mcm5U (5-methoxycarbonylmethyl uridine), mcm5s
CC       2U (5-methoxycarbonylmethyl-2-thiouridine), and ncm5U (5-
CC       carbamoylmethyl uridine). {ECO:0000250|UniProtKB:Q3E840}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[3Fe-4S](1+)-[protein] + Fe(2+)-[Dph3] = [3Fe-4S](0)-[protein]
CC         + Fe(3+)-[Dph3]; Xref=Rhea:RHEA:71235, Rhea:RHEA-COMP:17996,

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}.
