SER A:530
SER 530 IS ACETYLATED BY ASPIRIN (AN ACETYL GROUP IS COVALENTLY ATTACHED TO THE PROTEIN WHEN INHIBITED WITH ASPIRIN). THE ACETYLATED SER PREVENTS THE PROPER BINDING OF THE SUBSTRATE IN THE CYCLOOXYGENASE ACTIVE SITE. IT HAS BEEN RECENTLY SHOWN, HOWEVER, THAT ACETYLATION OF CYCLOOXYGENASE-2 RESULTS IN THE FORMATION OF A DIFFERENT PRODUCT (15-HETE).

Log
Note:
In this "Basic Interface" any change in the selection of a pulldown menu automatically triggers an action (one-step mechanism).
View and selection are coupled in the structure specific controls (e.g. "Hetero","PROSITE") .
Note:
In this "Advanced Interface" any change in the selection of a pulldown menu only sets the target for the corresponding control buttons (two-step mechanism).
View and selection are set independently in the structure specific controls (e.g. "Hetero","PROSITE") .
