Ligation and recutting results: After 2-10-fold BssH II overdigestion of 1 μg λ DNA substrate, results in 100% cutting, >95% of fragments can be ligated, and >95% recut.
Heat inactivation: Sensitive and inactivated at 80 °C for 20 minutes.
Comment: Optimal activity is at 50 °C

The properties and sources of all known class-I, class-II and class-III restriction endonucleases (ENases) and DNA modification methyltransferases (MTases) are listed and newly subclassified according to their sequence specificity. In addition, the enzymes are distinguished in a novel manner according

The role of certain amino acids in the interactions of ligands with their cognate nuclear receptors is usually achieved by the resolution of the crystal structure of the receptor complexed with the ligand. As a complementary functional approach, site-directed mutagenesis

Current next-generation sequencing (NGS) platforms adopt two types of sequencing mechanisms: by synthesis or by ligation. The former is employed by 454 and Solexa systems, while the latter by SOLiD system. Although the pros and cons for each sequencing mechanism

Targeted genome engineering requires nucleases that introduce a highly specific double-strand break in the genome that is either processed by homology-directed repair in the presence of a homologous repair template or by non-homologous end-joining (NHEJ) that usually results in insertions

Type IIB restriction-modification systems, such as BcgI, feature a single protein with both endonuclease and methyltransferase activities. Type IIB nucleases require two recognition sites and cut both strands on both sides of their unmodified sites. BcgI cuts all eight target
