| primase | <enzyme> The enzyme that polymerises nucleotide triphosphates to form oligoribonucleotides in a 5' to 3' direction. The enzyme synthesises the RNA for RNA DNA sequences that later become Okazaki fragments and also RNA primers for some types of phage using an sDNA template. (18 Nov 1997) |

| RNA primase | <enzyme, molecular biology> An RNA polymerase that synthesises a short RNA primer sequence to initiate DNA replication. (18 Nov 1997) |

| herpes simplex virus 1 helicase-primase | <enzyme> Complex of three herpes-encoded gene products (ul52, ul5, and ul8) in addition to helicase activity, contains a tightly associated complex that may prime lagging strand synthesis as it unwinds DNA at the viral replication fork Registry number: EC 3.1.- Synonym: hsv-1 helicase-primase, ul5 protein, hsv helicase-primase complex, ul52 protein, ul8 protein (26 Jun 1999) |
| DNA primase | <enzyme> A single-stranded DNA-dependent RNA polymerase that functions to initiate, or prime, DNA synthesis by synthesizing a nucleotide RNA polymer. Registry number: EC 2.7.7.- (12 Dec 1998) |
