A dichotomous family of Cache domain proteins evolved through c-type heme acquisition
Maithili Deshpande, Jiawei Xing, Vadim M. Gumerov…·Igor B. Zhulin
Cache sensor domains of DUF3365/Tll0287 family bind covalent c-type heme through a CXXCH insertion; a signaling member behaves like an NO sensor, a stand-alone one like a redox protein.
