Escherichia coli K-12 substr. MG1655 Reaction: 2.1.1.228

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Macromolecule Reactions Polynucleotide-Reactions RNA-Reactions tRNA-Reactions

EC Number: 2.1.1.228

Enzymes and Genes:
tRNA m1G37 methyltransferase Inferred from experiment : trmD

Supersedes EC number: 2.1.1.31

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: tRNA (guanine37-N1)-methyltransferase

Enzyme Commission Synonyms: TrmD, tRNA (m1G37) methyltransferase, transfer RNA (m1G37) methyltransferase, Trm5p, TRMT5, tRNA-(N1G37) methyltransferase, MJ0883 (gene name)

Enzyme Commission Summary:
This enzyme is important for the maintenance of the correct reading frame during translation. Unlike TrmD from Escherichia coli, which recognizes the G36pG37 motif preferentially, the human enzyme (encoded by TRMT5) also methylates inosine at position 37 [Brule04]. .
