Vanadate-Dependent Peroxidases in Macroalgae: Function, Applications, and Environmental Impact
With an average concentration of 35 nM, vanadium (essentially present in the form of ion pairs NaH2VO4 -) is the second-to-most abundant transition metal in sea water, outclassed only by molybdenum (present as molybdate MoO4 2−, ca. 100 nM). Vanadate-dependent haloperoxidases (VHPOs) can be present in marine brown, green and red algae, in (symbiotic) marine cyanobacteria, in Streptomyces bacter...
متن کاملPhycocyanin, cyanobacterial antioxidant: structure, function and applications
Phycobilins, open-chain tetrapyrrole pigment molecules, serve as accessory photosynthetic light-harvesting pigments in red algae and cyanobacteria. Phycobilin pigments are covalently linked with proteins and formed phycobiliproteins are organized into large macromolecular complexes called phycobilisomes on the top of the thylakoid membranes. In deep water, only green light is available, thus ph...
متن کاملVanadate Inhibits the ATP-dependent Degradation
Reticulocytes contain a nonlysosomal, ATP-dependent system for degrading abnormal proteins and normal proteins during cell maturation. Vanadate, which inhibits several ATPases including the ATP-dependent proteases in Escherichia coli and liver mitochondria, also markedly reduced the ATP-dependent degradation of proteins in reticulocyte extracts. At low concentrations (KI = 50 MM), vanadate inhi...
متن کاملMn(II) Regulation of Lignin Peroxidases and Manganese-Dependent Peroxidases from Lignin-Degrading White Rot Fungi.
Two families of peroxidases-lignin peroxidase (LiP) and manganese-dependent lignin peroxidase (MnP)-are formed by the lignin-degrading white rot basidiomycete Phanerochaete chrysosporium and other white rot fungi. Isoenzymes of these enzyme families carry out reactions important to the biodegradation of lignin. This research investigated the regulation of LiP and MnP production by Mn(II). In li...
متن کاملcompactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
