A novel zinc-binding fold in the helicase interaction
A novel zinc-binding fold in the helicase interaction domain of the Bacillus subtilis Dnal helicase loader Abstract The helicase loader protein DnaI (theBacillus subtilis homologue ofEscherichia coli DnaC) is required to load the hexameric helicase DnaC (theB. subtilis homologue ofE. coli DnaB) onto DNA at the start of replication. While the C-terminal domain of DnaI belongs to the

Nov 14, 2008 · DnaC AAA+ adopts a compact αβα fold typical of the core AAA+ nucleotide-binding domain, in which five parallel β-strands (β1–β5) are sandwiched on both sides by α-helices (α1–α2 on one face and α3–α7 on the other, Figure 1C) (Iyer et al., 2004).Because the sequence identity between DnaC and DnaA orthologs is only 15–20%, a value comparable to …

DnaC, the indispensable companion of DnaB helicase
Compared with these structures, 3D electron microscopic reconstructions of E.coli DnaB in a complex with DnaC sug-gests that this helicase is a spiral, but the NTD is constricted (43). In contrast, the crystal structure of GstDnaB complexed with the CTD of the cognate primase revealed that this DNA helicase is a closed ring, but its NTD is

Aug 05, 2003 · In Escherichia coli, the replicative DnaB helicase is a stabile hexamer over a wide range of protein concentrations and the E. coli DnaC loader is of the ring breaker class .EcDnaB is capable of self-loading onto single-strand DNA, but does so inefficiently. Efficient loading requires the EcDnaC helicase loader to facilitate opening of the ring, by holding the ring open and/or by …
