Altering the Regiospecificity of C6 Indole Prenyltransferase Enzymes Towards Drug Development
… previously as a L-tryptophan (L-Trp) C6 <em>C</em>-prenyltransferase (C6-<em>C</em>-PT). Analysis of PriB binding pocket, highlighted key residues that might play an important role in determining the regiospecificity of the enzyme and their mechanisms. Hence, we hypothesized that …

Roles of the P2X7 receptor in C6 astroglioma: in vitro and in vivo studies
… studied and in this work, I have used the rat C6 glioma as an experimental model system to investigate expression and function of the P2X7R in vitro and in vivo. The in vitro study has examined expression of the P2X7R in C6 cells and the involvement of this receptor in mediating cell functional …

Investigation of Biotransformation of 6:6 PFPiA into C6 PFPA during Anaerobic Digestion of Sludge
… in sludge can bio-transform 6:6 PFPiA into C6 PFPA during a 30-day anaerobic sludge digestion. Four samples were prepared to measure the microbial, non-biological, and abiotic degradation of 6:6 PFPiA in comparison to a sterile control sample. Over the 30-day digestion period, it was found …

C6 and C9 volatile compounds in 223 cucumbers (cucumis sativus L.) In Genome-Wide Association Studies (GWAS)
… varieties. This research aimed to quantify C6 and C9 compounds in 223 GWAS cucumber varieties. A comprehensive analysis of volatiles was performed using solid-phase microextraction gas chromatography-mass spectrometry (SPME-GC-MS). Hexenal (1.27–15.28 ppm) was the predominant volatile, …

Factors affecting the levels of 3-isobutyl-2-methoxypyrazine and C6 compounds in Vitis vinifera L. Merlot.
… the first study, the concentration of IBMP and C6 compounds in fruit harvested from 69 commercial vineyards located in three distinctly different wine grape growing regions were measured at commercial maturity from 2007 to 2010. Seasonal variation of green aromas was found to be more important …

Biochemical characterization of Cj 1123 c, a putative acetyltransferase & Cj 1319, a putative C6 dehydratase from Campylobacter jejuni.
Glycoproteins are important for the virulence of Campylobacter jejuni. The enzymes involved in protein glycosylation could provide new therapeutic targets. Two such proteins are Cjll23c, a putative acetyltransferase and Cj 1319, a putative GDP-mannose dehydratase encoded by the N- and O-linked …

The structural requirements of histone deacetylase (hdac) inhibitors: suberoylanilide hydroxamic acid (saha) analogues modified at c3, c6, and c7 positions enhance selectivity
… we theorized the substituents on the C3, C4, C5, C6, and C7 positions would display more potent inhibition compared to the C2-SAHA library due to the solvent exposed location. Interestingly, while the C2-SAHA analogues containing any substituents were poor potent, the C3-SAHA analogue with a …
