产品描述

Bialaphos is a natural non-selective phytotoxin produced by certain Streptomyces species. It is a pro-toxin, a tripeptide that is converted in vivo to the active agent phosphinothricin, which is a glutamine analog.[1] L-Phosphinothricin inhibits glutamine synthetase (Ki = 6.1 µM), resulting in accumulation of ammonium and disruption of primary metabolism.[1],[2] The bacterial bar gene encodes a phosphinothricin acetyltransferase, which confers resistance to phosphinothricin.[3] Bialaphos is used in the selection of transgenic plants that express the bar gene, usually under the control of a constitutively active viral promoter.[3]
