Rubrerythrin (RUBY) is a fusion protein containing an N-terminal diiron-binding domain (Pfam:PF02915) and a C-terminal rubredoxin-like domain. RUBY may play a role in oxidative stress. This entry represents the rubredoxin-like domain of RUBY and reverse rubrerythrin 1/2 from Clostridium acetobutylicum (RRBR1/2) [1-5]. RRBRs function as the terminal component of an NADH peroxidase when using NADH:rubredoxin oxidoreductase (NROR) as the electron transport intermediary from NADH to RRBRs and play an important role in the oxidative stress defense system of C. acetobutylicum [6].
