Rubrerythrin
From Wikipedia, the free encyclopedia
Rubrerythrin (RBR) is a non-heme iron-containing metalloprotein involved in oxidative stress tolerance within anaerobic bacteria.[1] It contains a di-iron active site, where peroxide is reduced into two water molecules, and a mono-iron rubredoxin-like domain thought to be involved in electron transfer.[2] A majority of known RBR families are utilized as peroxide "scavengers" to defend organisms against oxidative stress.
