CC -!- FUNCTION: Catalyzes the first step of diphthamide biosynthesis, a post-
CC translational modification of histidine which occurs in elongation
CC factor 2 (By similarity). Dph1 and dph2 transfer a 3-amino-3-
CC carboxypropyl (ACP) group from S-adenosyl-L-methionine (SAM) to a
CC histidine residue, the reaction is assisted by a reduction system
CC comprising dph3 and a NADH-dependent reductase (By similarity).
CC {ECO:0000250|UniProtKB:P40487, ECO:0000250|UniProtKB:Q5NCQ5}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-histidyl-[translation elongation factor 2] + S-adenosyl-L-
CC methionine = 2-[(3S)-amino-3-carboxypropyl]-L-histidyl-[translation
CC elongation factor 2] + H(+) + S-methyl-5'-thioadenosine;

CC Evidence={ECO:0000250|UniProtKB:Q5NCQ5};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000250|UniProtKB:P40487};
CC Note=Binds 1 [4Fe-4S] cluster per subunit. The cluster is coordinated
CC with 3 cysteines and an exchangeable S-adenosyl-L-methionine.
CC {ECO:0000250|UniProtKB:P40487};
CC -!- PATHWAY: Protein modification; peptidyl-diphthamide biosynthesis.
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 {ECO:0000250|UniProtKB:P40487}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q5NCQ5}. Cytoplasm
CC {ECO:0000250|UniProtKB:Q5NCQ5}.
CC -!- SIMILARITY: Belongs to the DPH1/DPH2 family. DPH1 subfamily.
CC {ECO:0000305}.
