probable diphthine methyl ester synthase [Brachypodium distachyon]

Protein Classification

diphthine methyl ester synthase( domain architecture ID 10794325)

diphthine methyl ester synthase is a 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

2-129 5.44e-10

N-terminal S-AdoMet-dependent tetrapyrrole methylase domain of Bacillus subtilis YabN and similar domains; This family includes the S-AdoMet (S-adenosyl-L-methionine or SAM)-dependent tetrapyrrole methylase (TP-methylase) domain of Bacillus subtilis YabN, and similar domains. YabN is a fusion of an N-terminal TP-methylase and a C-terminal MazG-type nucleotide pyrophosphohydrolase domain. MazG-like NTP-PPases have been implicated in house-cleaning functions such as degrading abnormal (d)NTPs. TP-methylases use S-AdoMet in the methylation of diverse substrates. Most TP-methylase family members catalyze various methylation steps in cobalamin (vitamin B12) biosynthesis, other members like diphthine synthase and ribosomal RNA small subunit methyltransferase I (RsmI) act on other substrates. The specific function of YabN's TP-methylase domain is not known.

precorrin-3B C17-methyltransferase; This model represents precorrin-3B C17-methyltransferase, one of two methyltransferases commonly referred to as precorrin-3 methylase (the other is precorrin-4 C11-methyltransferase, EC 2.1.1.133). This enzyme participates in the pathway toward the biosynthesis of cobalamin and related products. Members of this family may appear as fusion proteins with other enzymes of cobalamin biosynthesis.
