3.D.7.2.4
F420-non reducing hydrogenase subunits A, D and G of 472, 141, and 308 aas, respectively, with 0, 0 and 3-5 TMSs, respectively. It is a [NiFe] hydrogenase  and part of a complex that provides reducing equivalents for heterodisulfide reductase (Stojanowic et al. 2003). Also called HdrABC. This system is also found in Archeoglobus profundus DSM5631 (acc#s P84625, P84624, P84627) and Candidatus Prometheoarchaeum syntrophicum strain MK-D1 (Imachi et al. 2020).
