O-acyl isopeptide method: efficient synthesis of isopeptide segment and application to racemization-free segment condensation.
We report the establishment of the O-acyl isopeptide method-based racemization-free segment condensation reaction toward future chemical protein synthesis. Peptide segments containing C-terminal O-acyl Ser/Thr residues were successfully synthesized by use of a lower nucleophilic base cocktail for Fmoc removal, and then coupled to an amino group of a peptide-resin without side reactions or epime...
متن کاملA method for distinguishing 1-acyl from 2-acyl lysophosphatidylcholines generated in biological systems.
Phospholipases A(1) and A(2) frequently coexist in biological systems. Generation of lysophosphatidylcholine (LPC) in such systems cannot be assigned to any of these types of enzymes unless the position of the fatty acid in the lysocompound can be unambiguously determined. We here present a simple method to achieve this purpose. It is based on the initial chemical acylation of the isolated LPC ...
متن کاملA New Method for the Preparation of Acyl-CoA Thioesters1
A method is described for the preparation of CoA thioesters of fatty acids. AcylCoA thioester was synthesized by way of 1-acylimidazole and purified by high performance liquid chromatography. This method is applicable to the preparation of a variety of acyl-CoA thioesters of various chain lengths (from C2 to C18) and with varying degrees of unsaturation. It is particularly suitable for preparin...
متن کاملDevelopment of 1,2,4-triazole-5-thione derivatives as potential inhibitors of enoyl acyl carrier protein reductase (InhA) in tuberculosis.
Tuberculosis (TB) ranks second, next to AIDS making it most formidable disease if the present age. One of the crucial enzymes involved in cell wall synthesis of Mycobacterium tuberculosis, InhA (enoyl acyl carrier protein reductase) has been authenticated as an effective target for anti-mycobacterial drug development. In the current work, we have developed novel derivatives of 1,2,4-triazole-5-...
متن کاملDevelopment of an activity-based probe for acyl-protein thioesterases
Protein palmitoylation is a dynamic post-translational modification (PTM) important for cellular functions such as protein stability, trafficking, localization, and protein-protein interactions. S-palmitoylation occurs via the addition of palmitate to cysteine residues via a thioester linkage, catalyzed by palmitoyl acyl transferases (PATs), with removal of the palmitate catalyzed by acyl prote...
