Glucosyl transferase activity of bovine galactosyl transferase
Biochimica et Biophysica Acta (BBA) - General Subjects, 1978Bovine galactosyl transferase was found to utilize UDPglucose as a substrate and elicit disaccharide biosynthesis with glucose and N-acetylglucosamine as acceptors. The relative rate of glucosyl transferase with N-acetylglucosamine as acceptor was 0.3%, the rate for N-acetyllactosamine biosynthesis.

The flavin isoalloxazine ring in electron transferases functions in a redox capacity, being able to take up electrons from a donor to subsequently deliver them to an acceptor. The main characteristics of these flavoproteins, including their unique ability to mediate obligatory processes of two-electron transfers with those involving single-electron ...

Insect glutathione transferases
Drug Metabolism Reviews, 2011This article is an overview of the current knowledge of insect glutathione transferases. Three major topics are discussed: the glutathione transferase contributions to insecticide resistance, the polymorphic nature of the insect glutathione transferase superfamily, and a summary of the current structure-function studies on insect glutathione ...

Critical Reviews in Clinical Laboratory Sciences, 2001
Serum gamma-glutamyl transferase (GGT) has been widely used as an index of liver dysfunction and marker of alcohol intake. The last few years have seen improvements in these areas and advances in understanding of its physiological role in counteracting oxidative stress by breaking down extracellular glutathione and making its component amino acids ...

Enzymes are nature’s catalyst of choice for the highly selective and efficient coupling of carbohydrates. Enzymatic sugar coupling is a competitive technology for industrial glycosylation reactions, since chemical synthetic routes require extensive use of laborious protection group manipulations and often lack regio- and stereoselectivity.

Mosquito Glutathione Transferases
2005The glutathione transferases (glutathione S-transferases, GSTs) are a diverse family of enzymes involved in a wide range of biological processes, many of which involve the conjugation of the tripeptide glutathione to an electrophilic substrate. Relatively little is known about the endogenous substrates of mosquito GSTs, and most studies have focused on

Glutathione (GSH), the most ubiquitous and abundant nonprotein thiol, is essential in numerous detoxification reactions and is therefore considered a chemoprotectant. In the human, levels of GSH range from 30μM in plasma to 3mM in kidney proximal tubules; tumors of various organs can contain up to 10mM GSH [1].

Abstract The glutathione transferases (GSTs) are a family of multi-functional proteins which act as enzymes and also as binding proteins in detoxification processes (1-5). GSTs catalyse the nucleophilic attack of the sulfur atom of reduced glutathione by electrophilic groups in a second substrate.

[62] Animal sialic acid transferases (sialyl-transferases)
1966Publisher Summary This chapter discusses the synthesis of animal sialic acid transferases (sialyl-transferases). Sialic acids are generally found as constituents of heteropolymers, although one homopolysaccharide, colominic acid is isolated from Escherichia coli K-235.
