Barstar - Wikipedia

Barnase (a portmanteau of "BActerial" "RiboNucleASE") is a bacterial protein that consists of 110 amino acids and has ribonuclease activity. It is synthesized and secreted by the bacterium Bacillus amyloliquefaciens, but is lethal to the cell when expressed without its inhibitor barstar. The inhibitor binds to … 더 보기 Barnase has no disulfide bonds, nor does it require divalent cations or non-peptide components to fold. This simplicity, in combination with its reversible folding transition, means that barnase has been extensively studied in … 더 보기 Barnase catalyzes hydrolysis at diribonucleotide GpN sites. Cleavage occurs in two steps using a general acid-base mechanism: … 더 보기 • InterPro entry 더 보기 • Toxin-antitoxin system 더 보기 • Arcus VL, Vuilleumier S, Freund SM, Bycroft M, Fersht AR (September 1994).
