Methionine salvage pathway
WebMethionine salvage is a sequential pathway of six reactions that create methionine from 5'-methylthioadenosine (MTA) which is a byproduct of polyamine … WebThe methionine salvage pathway is a ubiquitous biochemical pathway (it is present in humans) that maintains methionine levels in vivo by recycling the thiomethyl- moiety of methionine through a degradation pathway that leads from AdoMet through methylthioadenosine (MTA).

An important salvage pathway is that from hypoxanthine to nucleotides. See HGPRT. From: salvage pathways in A Dictionary of Biomedicine ». Subjects: Science and technology — Chemistry. L-methionine salvage is the pathway that regenerates methionine from its downstream products. A version of the pathway uses methylthioadenosine (MTA), forming the so-called MTA cycle with its synthesizing reaction. This sulphur-recycling action is found in humans, and seems to be universal among aerobic life. Nicotinate salvage is the process of regenerating nicotinamide adenine dinucleotide from nicotini…
