THAP4 catalyzes the heme-based conversion of peroxynitrite into nitrate-NO3- in vitro [1]. At1g79260 is a nitrophorin-like heme-binding protein that may reversibly bind nitric oxide (NO) and be involved in NO transport [2]. This entry also includes the beta-barrel domain of Caenorhabditis elegans protein male abnormal 7 (Mab-7) which plays an important role in determining body shape and sensory ray morphology [3]. Nitrobindins (Nbs), constituting a heme-protein family spanning from bacteria to Homo sapiens, display an all-beta-barrel structural organisation. Proteins containing this domain are putatively related to fatty acid-binding proteins (FABPs) [4].
