It is used to treat infections caused by bacteria and toxoplasma gondii. Pharmacological action: antibiotics, macrolide, coccidiostats. Chemical name: Spiramycin (12 Dec 1998) |
| spiramycin I 3-hydroxyl acylase | <enzyme> Streptomyces ambofaciens enzyme prep able to acylate hydroxyl group at c-3 of lactone; no preference between acetyl-CoA and propionyl-CoA Registry number: EC 2.3.1.- Synonym: propionyl acylase (26 Jun 1999) |
