Protein
Diphthine methyl ester synthase 2
Organism
Candida albicans (strain SC5314 / ATCC MYA-2876)
Function
S-adenosyl-L-methionine-dependent methyltransferase that catalyzes four methylations of the modified target histidine residue in translation elongation factor 2 (EF-2), to form an intermediate called diphthine methyl ester. The four successive methylation reactions represent the second step of diphthamide biosynthesis.
Similarity
Belongs to the diphthine synthase family.
