Modification methylase PvuII

Gene

pvuIIM

Organism
Proteus hauseri
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

This methylase recognizes the double-stranded sequence CAGCTG, causes specific methylation on C-4 on both strands, and protects the DNA from cleavage by the PvuII endonuclease.

Catalytic activityi

S-adenosyl-L-methionine + DNA cytosine = S-adenosyl-L-homocysteine + DNA N(4)-methylcytosine.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
