This primase is structurally similar to many viral RNA-dependent RNA polymerases, reverse transcriptases, cyclic nucleotide generating cyclases and DNA polymerases of the A/B/Y families that are involved in DNA replication and repair.
Esta primase é estruturalmente similar a moitas ARN polimerases dependentes de ARN virais, transcritases inversas, ciclases xeradoras de nucleótidos cíclicos e ADN polimerases das familias A/B/Y que están implicadas na replicación e reparación do ADN.
