Metabolite Identification
Common NameGlyoxylic acid
DescriptionGlyoxylic acid, also known as glyoxylic acid or glyoxylic acid, belongs to the class of organic compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Glyoxylic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Glyoxylic acid exists in all living species, ranging from bacteria to humans. L-Alanine and glyoxylic acid can be converted into glycine and pyruvic acid; which is catalyzed by the enzyme serine--pyruvate aminotransferase. In cattle, glyoxylic acid is involved in the metabolic pathway called the alanine metabolism pathway. Glyoxylic acid is a potentially toxic compound.

Enzymes

General function:
Involved in copper ion binding
Specific function:
Bifunctional enzyme that catalyzes the post-translational modification of inactive peptidylglycine precursors to the corresponding bioactive alpha-amidated peptides, a terminal modification in biosynthesis of many neural and endocrine peptides (PubMed:2059626). Alpha-amidation involves two sequential reactions, both of which are catalyzed by separate catalytic domains of the enzyme. The first step, catalyzed by peptidyl alpha-hydroxylating monoxygenase (PHM) domain, is the copper-, ascorbate-, and O2- dependent stereospecific hydroxylation (with S stereochemistry) at the alpha-carbon (C-alpha) of the C-terminal glycine of the peptidylglycine substrate (PubMed:2059626). The second step, catalyzed by the peptidylglycine amidoglycolate lyase (PAL) domain, is the zinc-dependent cleavage of the N-C-alpha bond, producing the alpha-amidated peptide and glyoxylate (PubMed:2059626). Similarly, catalyzes the two-step conversion of an N-fatty acylglycine to a primary fatty acid amide and glyoxylate (By similarity).
