L-allo-threonine aldolase activity
Definition
Target type: molecularfunction
Catalysis of the reaction: L-allo-threonine = glycine + acetaldehyde. [PMID:9228760, RHEA:26209]
L-allo-threonine aldolase activity catalyzes the reversible aldol cleavage of L-allo-threonine to glycine and acetaldehyde. This enzyme is a member of the class I aldolases, which utilize a Schiff base mechanism for catalysis. The active site of L-allo-threonine aldolase contains a lysine residue that forms a Schiff base with the substrate, L-allo-threonine. This Schiff base intermediate is then cleaved to form glycine and an acetaldehyde-enzyme adduct. The acetaldehyde is then released from the enzyme, regenerating the active site lysine residue. L-allo-threonine aldolase is a key enzyme in the biosynthesis of L-allo-threonine, which is an important precursor for the synthesis of various amino acids and peptides. This enzyme has been found in a variety of organisms, including bacteria, fungi, and mammals.'

|---|---|---|---|
| oxaprozin | oxaprozin : A monocarboxylic acid that is a propionic acid derivative having a 4,5-diphenyl-1,3-oxazol-2-yl substituent at position 3. It is non-steroidal anti-inflammatory drug commonly used to relieve the pain and inflammatory responses associated with osteoarthritis and rheumatoid arthritis. Oxaprozin: An oxazole-propionic acid derivative, cyclooxygenase inhibitor, and non-steroidal anti-inflammatory drug that is used in the treatment of pain and inflammation associated with of OSTEOARTHRITIS; RHEUMATOID ARTHRITIS; and ARTHRITIS, JUVENILE. | 1,3-oxazoles; monocarboxylic acid | analgesic; non-steroidal anti-inflammatory drug |
| papaverine | papaverine : A benzylisoquinoline alkaloid that is isoquinoline substituted by methoxy groups at positions 6 and 7 and a 3,4-dimethoxybenzyl group at position 1. It has been isolated from Papaver somniferum. Papaverine: An alkaloid found in opium but not closely related to the other opium alkaloids in its structure or pharmacological actions. It is a direct-acting smooth muscle relaxant used in the treatment of impotence and as a vasodilator, especially for cerebral vasodilation. The mechanism of its pharmacological actions is not clear, but it apparently can inhibit phosphodiesterases and it may have direct actions on calcium channels. | benzylisoquinoline alkaloid; dimethoxybenzene; isoquinolines | antispasmodic drug; vasodilator agent |
| primaquine | primaquine : An N-substituted diamine that is pentane-1,4-diamine substituted by a 6-methoxyquinolin-8-yl group at the N(4) position. It is a drug used in the treatment of malaria and Pneumocystis pneumonia. Primaquine: An aminoquinoline that is given by mouth to produce a radical cure and prevent relapse of vivax and ovale malarias following treatment with a blood schizontocide. It has also been used to prevent transmission of falciparum malaria by those returning to areas where there is a potential for re-introduction of malaria. Adverse effects include anemias and GI disturbances. (From Martindale, The Extra Pharmacopeia, 30th ed, p404) | aminoquinoline; aromatic ether; N-substituted diamine | antimalarial |
