Metabolite Identification
Common Name3-Sulfinoalanine
Description3-Sulfinoalanine, also known as cysteine-S-dioxide or cysteine sulfinate, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. 3-Sulfinoalanine is possibly soluble (in water) and a very strong basic compound (based on its pKa). 3-Sulfinoalanine exists in all living species, ranging from bacteria to humans. 3-Sulfinoalanine participates in a number of enzymatic reactions, within cattle. In particular, 3-Sulfinoalanine can be biosynthesized from L-cysteine; which is mediated by the enzyme cysteine dioxygenase type 1. Furthermore, 3-Sulfinoalanine can be converted into hypotaurine through the action of the enzyme cysteine sulfinic acid decarboxylase. Furthermore, 3-Sulfinoalanine and oxoglutaric acid can be converted into 3-sulfinylpyruvic acid and L-glutamic acid through its interaction with the enzyme aspartate aminotransferase, cytoplasmic. Finally, 3-Sulfinoalanine can be biosynthesized from L-cysteine through its interaction with the enzyme cysteine dioxygenase type 1. In cattle, 3-sulfinoalanine is involved in a couple of metabolic pathways, which include the taurine and hypotaurine metabolism pathway and the cysteine metabolism pathway.

Enzymes

General function:
Amino acid transport and metabolism
Specific function:
Biosynthesis of L-glutamate from L-aspartate or L-cysteine. Important regulator of levels of glutamate, the major excitatory neurotransmitter of the vertebrate central nervous system. Acts as a scavenger of glutamate in brain neuroprotection. The aspartate aminotransferase activity is involved in hepatic glucose synthesis during development and in adipocyte glyceroneogenesis. Using L-cysteine as substrate, regulates levels of mercaptopyruvate, an important source of hydrogen sulfide. Mercaptopyruvate is converted into H(2)S via the action of 3-mercaptopyruvate sulfurtransferase (3MST). Hydrogen sulfide is an important synaptic modulator and neuroprotectant in the brain (By similarity).
