DNA primase has comparable affinities for ribonucleotides and deoxyribonucleotides. The Pabp41 subunit alone has no RNA synthesis activity but could synthesize long (up to 3 kb) DNA strands. Addition of the Pabp46 subunit increases the rate of DNA synthesis but decreases the length of the DNA fragments synthesized and confers RNA synthesis capability.

The primase complex preferentially interacts with dNTP rather than ribonucleoside triphosphates and initiates RNA as well as DNA chains de novo. The archaeal primase complex, in contrast to the eukaryote homolog, can initiate DNA chain synthesis in the absence of ribonucleoside triphosphates.

COMMENTARY
LITERATURE
evolution
the majority of primases are classified into two major groups, that is, the bacterial DnaG-type primases and the more complex eukaryotic primases. Archaea encode both types of DNA primase, they encode a eukaryotic-type primase comprising a catalytic subunit (PriS) and a noncatalytic subunit (PriL). Identification of a primase noncatalytic subunit, termed PriX, from the hyperthermophilic archaeon Sulfolobus solfataricus. Phylogenomic analysis, overview
metabolism
-
helicase is not essential but accelerates the reaction. HelpTN2 is a helicase of the SF1 family also encoded by pTN2 who enhances the PolpTN2-primed synthesis of dsDNA by PolB using M13mp18 as a template
physiological function
additional information
physiological function
at the initiation of chromosomal DNA replication, DNA primases synthesize short RNA primers, which are subsequently elongated by DNA polymerases
physiological function
Q9V292; Q9V291
the heterodimeric primase complex is necessary for archaeal survival
physiological function
-
DNA primase PolpTN2 and DNA polymerase PolB are essential for synthesis of dsDNA from deoxynucleotide triphosphates by producing an oligonucleotide primer. The first step of template-free DNA synthesis may involve the creation of seeds by PolpTN2 primase, which are subsequently amplified in synergy with PolB. Template?free synthesis is highly temperature?dependent
physiological function
DNA primases play a critical role in the initiation of DNA replication by synthesizing RNA primers on both the leading and lagging strands since DNA polymerases are incapable of de novo DNA synthesis. Product synthesis by PriSL in the presence of PriX, the Sso0502 product, is over an order of magnitude (about 16fold) more efficient than that in its absence. PriX and PriL bind template DNA differently. Both PriSX and PriSLX differ from PriSL in primer synthesis, overview. PriL but not PriX enhances primer extension by PriS
additional information
the catalytic activity of PriS is modulated through concerted interactions with the two noncatalytic subunits in primer synthesis. The catalytic activity of PriS is modulated through concerted interactions with the two noncatalytic subunits in primer synthesis. PriX subunit residues 26-54 are in a flexible region. PriX residues 55-154 fold into a single domain containing 6 helices, which form a compact core stabilized by extensive hydrophobic interactions. The overall structure of the PriX protein is quite unique

LITERATURE
heterodimer
heterotrimer
archaea encode a eukaryotic-type primase comprising a catalytic subunit, PriS, and a noncatalytic subunit, PriL and PriX. PriX is a diverged homologue of the C-terminal domain of PriL but lacks the iron-sulfur cluster. PriX, PriL and PriS form a stable heterotrimer (PriSLX). Both PriSX and PriSLX show far greater affinity for nucleotide substrates and are substantially more active in primer synthesis than the PriSL heterodimer. PriL, but not PriX, facilitates primer extension by PriS. The catalytic activity of PriS is modulated through concerted interactions with the two noncatalytic subunits in primer synthesis. PriX subunit residues 26-54 are in a flexible region. PriX residues 55-154 fold into a single domain containing 6 helices, which form a compact core stabilized by extensive hydrophobic interactions. The overall structure of the PriX protein is quite unique, sequence and three-dimensional structure comparisons, overview

The crystals belong to the P3(2)21 with unit-cell parameters a = b = 77.8, c = 129.6 A, and alpha = beta = 90°, gamma = 120°. Crystals of the selenomethionine derivative are obtained by means of a cross-seeding method using native crystals. The data for the native and selenomethionine-substituted crystals are collected to 1.8 and 2.2 A resolution
hanging drop vapor diffusion at 18°C, the structure provides the first three-dimensional description of the large subunit and its interaction with the small subunit

structure-function analysis of the pRN1 primase-polymerase domain. The crystal structure shows a central depression lined by conserved residues. Mutations on one side of the depression reduce DNA affinity. On the opposite side of the depression cluster three acidic residues and a histidine, which are required for primase and DNA polymerase activity. One acidic residue binds a manganese ion, suggestive of a metal-dependent catalytic mechanism. The structure does not show any similarity to DNA polymerases, but is distantly related to archaeal and eukaryotic primases, with corresponding active-site residues
