A hallmark of penicillin-binding protein 2 (PBP2) from penicillin-resistant strains of Neisseria gonorrhoeae is insertion of an aspartate after position 345. The insertion resides on a loop near the active site and is immediately adjacent to an existing aspartate (Asp346)

Secondary transporters in the excitatory amino acid transporter family terminate glutamatergic synaptic transmission by catalyzing Na(+)-dependent removal of glutamate from the synaptic cleft. Recent structural studies of the aspartate-specific archaeal homolog, Glt(Ph), suggest that transport is achieved by a rigid

Experimental and clinical studies give evidence for breakdown of membrane phospholipids during neurodegeneration. In the present study, we measured the levels of glycerophosphocholine (GPCh), phosphocholine (PCh), and choline, that is, water-soluble metabolites of phosphatidylcholine (PtdCho), in human cerebrospinal fluid (CSF).

We developed a method for the determination of serum 5alpha-cholestan-3beta-ol (cholestanol). The sterols were derivatized to the 4'-bromobenzenesulfonyl esters and heated in isopropanol. The cholesterol-4'-bromobenzenesulfonate was solvolyzed to cholesteryl isopropyl ether, but the derivatized cholestanol did not change and could
