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 (By similarity). Facilitates the
CC reduction of the catalytic iron-sulfur cluster found in the DPH1
CC subunit (By similarity). {ECO:0000250|UniProtKB:P32461}.
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000250|UniProtKB:P32461};
CC Note=Binds 1 [4Fe-4S] cluster per subunit. The cluster facilitates the
CC reduction of the catalytic iron-sulfur cluster in the DPH1 subunit.
CC {ECO:0000250|UniProtKB:P32461};
CC -!- PATHWAY: Protein modification; peptidyl-diphthamide biosynthesis.
CC {ECO:0000250|UniProtKB:P32461}.
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:P32461}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P32461}.
CC -!- SIMILARITY: Belongs to the DPH1/DPH2 family. DPH2 subfamily.
CC {ECO:0000305}.
