IPR030390
RNA methyltransferase TrmA, active site
InterPro entry
Short name | MeTrfase_TrmA_AS |
Description
* Escherichia coli hypothetical protein ygcA and HI0333, the corresponding Haemophilus influenzae protein.
* Haemophilus influenzae hypothetical protein HI0958.
* Chlamydia trachomatis protein HOM1.
* Fission yeast hypothetical protein SpAC4G8.07c.
It is probable that ygcA/HI0333 and HI0958 are responsible for the methylation of U747 and U1939 in 23S rRNA. In trmA, a cysteine is known to participate in the catalytic mechanism by forming a covalent adduct to C6 of uracil.
This entry represents a conserved region that includes the active site cysteine.
