Proteolysis of HCF-1 by Ser/Thr glycosylation-incompetent O-GlcNAc transferase:UDP-GlcNAc complexes.
In complex with the cosubstrate UDP-N-acetylglucosamine (UDP-GlcNAc),O-linked-GlcNAc transferase (OGT) catalyzes Ser/ThrO-GlcNAcylation of many cellular proteins and proteolysis of the transcriptional coregulator HCF-1. Such a dual glycosyltransferase-protease activity, which occurs in the same active site, is unprecedented and integrates both reversible and irreversible forms of protein post-t...
The structural domains of human apolipoprotein B-100 in low density lipoproteins (LDL) and the conformational changes of B-100 that accompany the conversion of very low density lipoproteins (VLDL) to LDL were investigated by limited proteolysis with 12 endoproteases of various specificities, and their cleavage sites were determined. In B-100 of LDL, we identified two peptide regions that are hi...
Akaraet--The structural and functional domains of Escherichia coil carbamoyl phosphate synthetase (CPS) have been identified by limited proteolysis. Incubation of CPS with several proteases, including trypsin, chymotrypsin, subtilisin and endoproteinase Asp-N, under native conditions, causes a time-dependent loss of enzymatic activity and the generation of a common fragmentation pattern. Amino-...
