Sysname
S-adenosyl-L-methionine:2-[(3S)-3-carboxy-3-aminopropyl]-L-histidine-[translation elongation factor 2] methyltransferase (diphthine methyl ester-[translation elongation factor 2]-forming)
Reaction(IUBMB)
4 S-adenosyl-L-methionine + 2-[(3S)-3-carboxy-3-aminopropyl]-L-histidine-[translation elongation factor 2] = 4 S-adenosyl-L-homocysteine + diphthine methyl ester-[translation elongation factor 2] [RN:
R11165 ]
Reaction(KEGG)
Substrate
S-adenosyl-L-methionine [CPD:
C00019 ];
2-[(3S)-3-carboxy-3-aminopropyl]-L-histidine-[translation elongation factor 2] [CPD:
C04441 ]
Product
S-adenosyl-L-homocysteine [CPD:
C00021 ];
diphthine methyl ester-[translation elongation factor 2] [CPD:
C21151 ]
Comment
This eukaryotic enzyme is part of the biosynthetic pathway of diphthamide. Different from the archaeal enzyme, which performs only 3 methylations, producing diphthine (cf. EC
2.1.1.98 ). The relevant histidine of elongation factor 2 is His715 in mammals and His699 in yeast. The order of the 4 methylations is not known.
History
