Hexameric Replicative Helicase RepA of plasmid RSF1010 and related proteins
This family includes the homo-hexameric replicative helicase RepA encoded by plasmid RSF1010. RSF1010 is found in most Gram-negative bacteria and some Gram-positive bacteria . The RepA protein of Plasmid RSF1010 is a 5'-3' DNA helicase which can utilize ATP, dATP, GTP and dGTP (and CTP and dCTP to a lesser extent).
