Abstract

Synonym(s): 6-O-methylguanine-DNA methyltransferase, O-6-methylguanine-DNA-alkyltransferase

This entry represents the DNA binding region of 6-O-methylguanine-DNA methyltransferases.

The repair of DNA containing O6-alkylated guanine is carried out by DNA-[protein]-cysteine S-methyltransferase . The major mutagenic and carcinogenic effect of methylating agents in DNA is the formation of O6-alkylguanine. The alkyl group at the O-6 position is transferred to a cysteine residue in the enzyme [PubMed3052269]. This is a suicide reaction since the enzyme is irreversibly inactivated and the methylated protein accumulates as a dead-end product. Most, but not all of the methyltransferases are also able to repair O-4-methylthymine. DNA-[protein]-cysteine S-methyltransferases are widely distributed and are found in various prokaryotic and eukaryotic sources [PubMed1579490].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 3 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Methylated DNA-protein cysteine methyltransferase, C-terminal domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 3 hidden Markov models representing the Methylated DNA-protein cysteine methyltransferase, C-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
