This alpha helical domain is found in a set of bacterial plasmid replication proteins [1]. The domain is found to the C-terminus of the primase/polymerase domain. Mutants of this domain are defective in template binding, dinucleotide formation and conformation change prior to DNA extension [1].	Domain
