Alanine is the simplest α-amino acid after glycine. The methyl side-chain of alanine is non-reactive and is therefore hardly ever directly involved in protein function. [12] Alanine is a nonessential amino acid, meaning it can be manufactured by the human body, and does not need to be obtained through the diet. Alanine is found in a wide ...
Cysteic acid also known as 3-sulfo-l-alanine is the organic compound with the formula HO 3 SCH 2 CH(NH 2)CO 2 H. It is often referred to as cysteate, which near neutral pH takes the form − O 3 SCH 2 CH(NH 3 +)CO 2 −. It is an amino acid generated by oxidation of cysteine, whereby a thiol group is fully oxidized to a sulfonic acid/sulfonate ...
L-aspartate L-alanine + CO 2. Hence, this enzyme has one substrate, L-aspartate, and two products, L-alanine and CO 2. This reaction is the basis of the industrial synthesis of L-alanine. [1] This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds.
The enzyme pyrazolylalanine synthase (EC 4.2.1.50) catalyzes the chemical reaction. L-serine + pyrazole 3-(pyrazol-1-yl)-L-alanine + H 2 O. This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds.
The systematic name of this enzyme class is L-selenocysteine selenide-lyase (L-alanine-forming). Other names in common use include selenocysteine reductase, and selenocysteine β-lyase. Other names in common use include selenocysteine reductase, and selenocysteine β-lyase.
These four Mur ligases are responsible for the successive additions of L-alanine, D-glutamate, meso-diaminopimelate or L-lysine, and D-alanyl-D-alanine to UDP-N-acetylmuramic acid. All four Mur ligases are topologically similar to one another, even though they display low sequence identity.
Thus, the two substrates of this enzyme are O3-acetyl-L-serine and pyrazole, whereas its two products are 3-(pyrazol-1-yl)-L-alanine and acetate. This enzyme belongs to the family of transferases , specifically those transferring aryl or alkyl groups other than methyl groups.
Nopalinic acid (also named ornaline) (N 2-(D-1,3-dicarboxypropyl)-L-ornithine) is a member of the nopaline family found in crown gall tumors. Octopine. Octopine (N 2-(D-1-carboxyethyl)-L-arginine) is the first opine discovered in 1927 in octopus muscle and later in crown gall tumors. It is also found in other cephalopod species and lamellibranchs.
