A model of the T4 bacteriophage DNA replisome. Replication of T4 genomic DNA is accomplished by a replication complex composed of eight proteins. The helicase (gp41) and primase (gp61) interact to form the primosome with the assistance of the helicase loader (gp59).

Investigation of stoichiometry of T4 bacteriophage helicase loader protein (gp59). Arumugam S.R., Lee T.H., Benkovic S.J. The T4 bacteriophage helicase loader (gp59) is one of the main eight proteins that play an active role in the replisome. gp59 is a small protein (26 kDa) that exists as a monomer in solution and in the crystal.

The function of HROB in HR is reminiscent of that of gp59, which acts as the replicative helicase loader during bacteriophage T4 recombination-dependent DNA replication. We therefore propose that the loading of MCM8-MCM9 by HROB may similarly be a key step in the establishment of mammalian recombination-associated DNA synthesis.

Nov 21, 2001 · The gene product 61 primase protein from bacteriophage T4 was expressed as an intein fusion and purified to homogeneity. The primase binds one zinc ion, which is coordinated by four cysteine residues to form a zinc ribbon motif. Factors that influence the rate of priming were investigated, and a physiologically relevant priming rate of ∼1 primer per second per primosome was achieved.

Jul 30, 2021 · The reconstitution of the T4 DNA replication elongation complex in vitro requires eight proteins: the gp43 DNA Pol, the gp45 clamp, the gp44/gp62 clamp loader, the gp41 Hel, the gp59 Hel loader, the gp61 primase, and the gp32 ssDNA-binding protein [48,49]. A holo-replicase complex (T4 Pol) comprises gp43 and gp45.

comparison to related proteins when the T4 structures are unavailable. Three of the ten full-length T4 replisomal proteins have been determined; the gp59 helicase loading protein, the RNase H, and the gp45 processivity clamp. The core of T4 gp32 and two proteins from the T4 related phage RB69, the gp43 polymerase and the gp45 clamp are also solved.
