FAMILY

nitrite and sulfite reductase 4Fe-4S domain family

DESCRIPTION

Also known as SIR_MAIZE, SIR. Essential protein with sulfite reductase activity required in assimilatory sulfate reduction pathway during both primary and secondary metabolism and thus involved in development and growth., DNA-binding protein that binds to both double-stranded and single-stranded DNA without significant sequence specificity to reversibly repress the transcriptional activity of chloroplast nucleoids by promoting DNA compaction and possibly regulate DNA replication. Monomer (By similarity). Interacts with ferredoxin.
