| sphingomyelin deacylase | <enzyme> Forms sphingosylphosphocholine Registry number: EC 3.5.1.- Synonym: sm-deacylase (26 Jun 1999) |

| sphingomyelin | <biochemistry> A sphingolipid in which the head group is phosphoryl choline. A close analogue of phosphatidylcholine. In many cells the concentration of sphingomyelin and phosphatidylcholine in the plasma membrane seems to bear a reciprocal relationship. (18 Nov 1997) |
|---|---|
| sphingomyelin lipidosis | <disease> A family of severe lysosomal storage diseases resulting in an accumulation of sphingomyelin and other phospholipids in the reticuloendothelial system. The best studied forms are due to deficiency of sphingomyelinase and it is more common in Ashkenazi Jews than other groups. Clinical signs include foam cells in the blood and marrow, hepatosplenomegaly and neurologic degeneration. Diagnosis is confirmed by enzyme assay on leukocytes or fibroblasts and specific mutations in the gene are now recognised. (29 Dec 1997) |
| sphingomyelin phosphodiesterase | <enzyme> An enzyme that catalyses the hydrolysis of sphingomyelin to ceramide (n-acylsphingosine) plus choline phosphate. A defect in this enzyme leads to niemann-pick disease. Chemical name: Sphingomyelin cholinephosphohydrolase Registry number: EC 3.1.4.12 (12 Dec 1998) |
| lecithin/sphingomyelin ratio | A ratio used to determine foetal pulmonary maturity, found by testing the amniotic fluid; when the lungs are mature, lecithin exceeds sphingomyelin by 2 to 1. (05 Mar 2000) |
| acetyl-CoA deacylase | <enzyme> An enzyme that catalyses reversibly the hydrolysis of acetyl-CoA to yield CoA and acetate. The enzyme is involved in the oxidation of fatty acids. Chemical name: Acetyl-CoA hydrolase Registry number: EC 3.1.2.1 (12 Dec 1998) |
| C-13-deacylase | <enzyme> An extracellular enzyme that specifically removes the c-13 side chain from paclitaxel and other taxanes to produce baccatin-iii; produced by nocardioides albus; mw 47 kD Registry number: EC 3.1.1.- Synonym: c13-deacylase (26 Jun 1999) |
| sphingolipid ceramide N-deacylase | <enzyme> Hydrolyzes the n-acyl linkage between fatty acids and sphingosine bases in ceramides in various sphingolipids, as well as sphingomyelin to produce their lyso forms; mw 52 kD Registry number: EC 3.5.1.- Synonym: scdase (26 Jun 1999) |
| N-acyl-D-glutamate deacylase | <enzyme> Substrate specificity is for short chain acyl glutamates, including n-formyl-d-glutamate, n-chloroacetyl-d-glutamate and n-acetyl-d-glutamate Registry number: EC 3.5.1.- Synonym: n-acyl-d-glutamate amidohydrolase, d-agase (26 Jun 1999) |
| deacylase | 1. A member of the subclass of hydrolases (EC class 3), especially of that subclass of esterases, lipases, lactonases, and hydrolases (EC subclass 3.1). 2. Any enzyme catalyzing the hydrolytic cleavage of an acyl group (R-CO-) in an ester linkage; also includes enzymes cleaving amide linkages (EC subclass 3.5) and similar acyl compounds. (05 Mar 2000) |
| long-chain-fatty-acyl-glutamate deacylase | <enzyme> Lca aminoacylase I almost specific to l-glutamate-containing lipoamino acids; lca aminoacylase II acts on fatty acyl amino acids with chain lengths between c11 and c16 Registry number: EC 3.5.1.55 Synonym: lca aminoacylase I, lca aminoacylase II, n-long chain acyl aminoacylase (26 Jun 1999) |
