3-Methylcrotonylglycine is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction: acyl-CoA + glycine < -- > CoA + N-acylglycine. 3-Methylcrotonylglycine is a normal amino acid metabolite found in urine. Increased levels of this metabolite are found in patients suffering from leucine catabolic disorders, such as 3-methylcrotonyl-CoA carboxylase deficiency. 3-Methylcrotonylglycine is often considered to be a diagnostic marker of organic acidemias (PMID 11170888). Moreover, 3-methylcrotonylglycine is found to be associated with 3-hydroxy-3-methylglutaryl-CoA lyase deficiency and propionic acidemia, which are also inborn errors of metabolism. 3-Methylcrotonylglycine is an acyl glycine.

2-Aminomuconic acid

(2Z,4E)-5-aminohexa-2,4-dienedioic acid

2-Aminomuconic acid is a product of the Tryptophan metabolism degradation pathway (kinurenine pathway), in a reaction catabolized by the enzyme aminocarboxymuconate semialdehyde decarboxylase [EC:4.1.1.45]. The kynurenine pathway is the major route of L-tryptophan degradation in mammals.

Paramethadione

5-ethyl-3,5-dimethyl-1,3-oxazolidine-2,4-dione

Paramethadione is only found in individuals that have used or taken this drug. It is an anticonvulsant in the oxazolidinedione class. It is associated with fetal trimethadione syndrome, which is also known as paramethadione syndrome.Dione anticonvulsants such as paramethadione reduce T-type calcium currents in thalamic neurons (including thalamic relay neurons). This inhibits corticothalamic transmission and raises the threshold for repetitive activity in the thalamus. This results in a dampening of the abnormal thalamocortical rhythmicity proposed to underlie the 3-Hz spike-and-wave discharge seen on electroencephalogram (EEG) during absence seizures.

Tiglylglycine is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation.

Tiglylglycine is an intermediate product of the catabolism of isoleucine. An elevated level of tiglylglycine is identified in urine of patients with beta-ketothiolase deficiency or with disorders of propionate metabolism (PMID 7923765).

N-Acetylproline

(2S)-1-Acetylpyrrolidine-2-carboxylic acid

N-Acetyl-L-proline or N-Acetylproline, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetylproline can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetylproline is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-proline. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\% of all human proteins and 68\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT‚Äôs (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylproline can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free proline can also occur. Many N-acetylamino acids, including N-acetylproline are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557).
