A rapid method for enzymatic preparation of 3'-phosphoadenosine-5'-phosphosulfate (PAPS) is described. The method uses rat liver as the source of the PAPS synthesizing enzymes, and requires 2 days for production of 98 to 151 pmol of purified coenzyme. Purification of crude PAPS begins with ion-excha
Several 13-azasteroidal heterocyclics3 4 , including 13-azaequilenin , have been synthesized recently. The synthesis of a. 13-a.zaestrone derivative will be the subject of this communication.
## Abstract Certain fungi of the genus Didymella were detected which are particularly suitable for the enzymatic introduction of an 1,2βdoubleβbond into Ξ^4^β3βketoβsteroids. In this way a number of new 1βdehydroβsteroids have been prepared.
