UniProtKB - P25282 (MTG1_AVIPA)
Protein
Modification methylase HgaIA
Gene
hgaIAM
Organism
Avibacterium paragallinarum (Haemophilus gallinarum)
Status
Functioni
This methylase recognizes the strands carrying the 5'-GCGTC-3' sequence, causes specific methylation on C-2, and protects the DNA from cleavage by the HgaI endonuclease.
Miscellaneous
The HgaI modification system consists of two cytosine methylase genes responsible for modification of different strands in the target DNA.
Catalytic activityi
