High level of sial- ate-O-acetyltransferase activity in lymphoblasts of childhood acute lymphoblastic leukaemia (ALL): enzyme characterization and corre- lation with disease status [J]. Glycoconj J, 2009, 26(1): 57-73.Mandal C, Srinivasan GV, Chowdhury S, Chandra S, Mandal C, Schauer R, ...
Activity assays of recombinant proteins demonstrated that all twelve PtrXOAT proteins were able to transfer acetyl groups from acetyl CoA onto a xylohexaose acceptor with PtrXOAT1, PtrXOAT2, PtrXOAT3, PtrXOAT11 and PtrXOAT12 having the highest activity. Structural analysis of the PtrXOAT-...
A radiochemical assay is described for the measurement of corticosteroid-21-0-acetyltransferase activity in the soluble protein fraction of homogenates of baboon brain. A high yield of the enzyme is obtained when homogenization is performed with a pH 6.4 buffer containing 0.15M NaCl, 50 mM thioglyc...
Except for the chewing-tobacco extract on TA98 without S9, positive activity was found in both nitrosated tobacco extracts on YG1024 and TA98. As with the coal extracts, the presence of nitroarenes was inferred for these nitrosated materials. A comparative study of the non-nitrosated snuff ...

Obesity and lipid stress inhibit carnitine acetyltransferase activity Carnitine acetyltransferase (CrAT) is a mitochondrial matrix enzyme that catalyzes the interconversion of acetyl-CoA and acetylcarnitine. Emerging evidence... SE Seiler,OJ Martin,RC Noland,... - 《Journal of Lipid Research》 被引量:...
Biochemical analyses showed that several hairy root lines expressed high levels of DAT enzyme activity compared to control hairy root cultures expressing 尾-gulucuronidase activity (GUS) activity. Metabolite analysis using high performance liquid chromotagraphy established that hairy root extracts had an...
It is generally accepted that the highly conserved HXXXD motif is crucial for the activity of BAHD members43. The motif has also been found in the DBAT structure, in which His162 most likely acts as a catalytic site (Fig. 4b). In addition, the structure of the solvent channel of BAHD...

This activity was found to be dependent upon a second protein, which functions to translocate acetate from the cytoplasm to the periplasm, demonstrating that the O-acetylation of peptidoglycan in N. gonorrhoeae, and other gram-negative bacteria, requires a two component system. 展开 ...
