A novel biosynthetic pathway towards isothiocyanate natural products is identified. In vivo and in vitro biotransformation show that rhodanese-like proteins (Rhd), known for the detoxification of cyanide, have been recruited and neofunctionalized to catalyze sulfur incorporation into isonitriles in bacteria. This so far unknown function of rhodanese-like proteins is highly specific and plays a key
确定了异硫氰酸酯天然产物的新生物合成途径。体内和体外生物转化表明,以氰化物解毒而闻名的硫氰酸样蛋白(Rhd)已被招募并新功能化以催化细菌中的硫掺入异腈。硫氰酸酶样蛋白的这种迄今为止未知的功能具有高度特异性,并且在来自剑兰伯克霍尔德菌的抗真菌芥子苷的生物合成中发挥关键作用。
