  • Barstar — is a small protein synthesized by the bacterium Bacillus amyloliquefaciens . Its function is to inhibit the ribonuclease activity of its binding partner barnase, with which it forms an extraordinarily tightly bound complex within the cell until… …   Wikipedia

  • barnase — A bacterial ribonuclease, which, when transformed into plants and expressed in the anthers, generates a male sterile phenotype. Thus it is a technology applicable to F1 hybrid seed production, which relies on the ability to genetically sterilize… …   Glossary of Biotechnology

  • Enzyme inhibitor — Enzyme inhibitors are molecules that bind to enzymes and decrease their activity. Since blocking an enzyme s activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. They are also used as herbicides and… …   Wikipedia

  • Barnase — 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… …   Wikipedia

  • Bacillus amyloliquefaciens — is a species of bacteria that is the source of the BamH1 restriction enzyme. It also synthesizes a natural antibiotic protein barnase, a widely studied ribonuclease that forms a famously tight complex with its intracellular inhibitor… …   Wikipedia
