SgrAI is a type IIF restriction endonuclease that cuts an unusually long recognition sequence and exhibits allosteric self-modulation of cleavage activity and sequence specificity. Previous studies have shown that DNA bound dimers of SgrAI oligomeriz

The evolutionary spread of 22 fibronectin type III (Fn3) sequences among a dozen bacterial enzymes has been traced by searching databases with the non-Fn3 parts of the enzyme sequences. Numerous homologues were found that lacked the Fn3 domains. In e
SgrAI is a type II restriction endonuclease that cuts an unusually long recognition sequence and exhibits allosteric self-activation with expansion of DNA-sequence specificity. The three-dimensional crystal structures of SgrAI bound to cleaved primar

SummaryControl of replication, transcription, recombination and repair requires proteins capable of finding particular DNA sequences in a background of a large excess of nonspecific sequences. Such recognition can involve direct readout, with direct

Uninterpretable electron-density maps were obtained using either MIRAS phases or MR phases in attempts to determine the structure of the type II restriction endonuclease SgrAI bound to DNA. While neither solution strategy was particularly promising (
Five new structures of the Q138F HincII enzyme bound to a total of three different DNA sequences and three different metal ions (Ca{sup 2+}, Mg{sup 2+}, and Mn{sup 2+}) are presented. While previous structures were produced from soaking Ca{sup 2+} in

The three-dimensional X-ray crystal structure of the ‘rare cutting’ type II restriction endonuclease SgrAI bound to cognate DNA is presented. SgrAI forms a dimer bound to one duplex of DNA. Two Ca2+ bind in the enzyme active site, with one ion at

The 2.1A crystal structure of the unliganded type II restriction endonuclease, HincII, is described. Although the asymmetric unit contains only a single monomer, crystal lattice contacts bring two monomers together to form a dimer very similar to tha
