Prostaglandin (PG) E1 enhances formation of 3H-adenosine-3',5'-cyclic monophasphate (3H-cAMP) in platelets pulse-labeled with 3H-adenine. This response was assessed as an index of receptor sensitivity and of PG function. Prostagladin E1-stimulated 3H-cAMP accumulation in paltelets from schizophrenics was significantly reduced compared with control subjects.(More)
The membrane penicillinase of Bacillus licheniformis 749/C is a phospholipoprotein which differs from the exoenzyme in that it has an additional sequence of 24 amino acid residues and a phosphatidylserine at the NH2 terminus. In exponential-phase cultures, the conversion of membrane penicillinase to exoenzyme occurs at neutral and alkaline pH. An enzyme(More)
In earlier studies of the membrane-bound penicillinase of Bacillus licheniformis 749/C, the enzyme present in the vesicles that were released during protoplast formation and the enzyme retained in the plasma membrane of protoplasts appeared to differ (i) in their behavior on gel permeation chromatography in the presence or absence of deoxycholate and (ii)(More)
