abstract = {The restriction endonuclease (REase) NgoAVII iscomposed of
two proteins, R.NgoAVII and N.NgoAVII,and shares features of
both Type II restriction en-zymes and Type I/III
ATP-dependent restriction en-zymes (see accompanying paper
Zaremba et al.,2014). Here we present crystal structures of
theR.NgoAVII apo-protein and the R.NgoAVII C-terminaldomain
bound to a specific DNA. R.NgoAVII is com-posed of two
domains: an N-terminal nucleolytic PLDdomain; and a
C-terminal B3-like DNA-binding do-main identified previously
in BfiI and EcoRII REases,and in plant transcription
factors. Structural compar-ison of the B3-like domains of
R.NgoAVII, EcoRII, BfiIand the plant transcription factors
revealed a con-served DNA-binding surface comprised of N-
andC-arms that together grip the DNA. The C-arms
ofR.NgoAVII, EcoRII, BfiI and plant B3 domains are sim-ilar
in size, but the R.NgoAVII N-arm which makes themajority of
the contacts to the target site is muchlonger. The overall
structures of R.NgoAVII and BfiIare similar; however, whilst
BfiI has stand-alone cat-alytic activity, R.NgoAVII requires
an auxiliary cog-nate N.NgoAVII protein and ATP hydrolysis
in or-der to cleave DNA at the target site. The structureswe
present will help formulate future experiments toexplore the
molecular mechanisms of intersubunitcrosstalk that control
DNA cleavage by R.NgoAVIIand related endonucleases.},
