Protein

DNA gyrase subunit A

Gene

gyrA

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

Functioni

DNA gyrase negatively supercoils closed circular double-stranded DNA in an ATP-dependent manner and also catalyzes the interconversion of other topological isomers of double-stranded DNA rings, including catenanes and knotted rings.By similarity

Catalytic activityi

ATP-dependent breakage, passage and rejoining of double-stranded DNA.

Post-translational modificationi

This protein undergoes a protein self splicing that involves a post-translational excision of the intervening region (intein) followed by peptide ligation.

Keywords - PTMi

Autocatalytic cleavage, Protein splicing

Interactioni

Subunit structurei

Heterotetramer, composed of two GyrA and two GyrB chains. Within the heterotetramer, GyrA contains the active site tyrosine that forms a covalent intermediate with the DNA, while GyrB contributes the cofactor binding sites and catalyzes ATP hydrolysis (By similarity).By similarity
