Substrate Specificity of Mycodextranase

Nature, 1966
MYCODEXTRAN (nigeran) is an unbranched polysaccharide composed of a regular alternating sequence of α–(1rarr;3) and α–(1→4) linked glucopyranosyl units. It is produced in the mycelia of various species of moulds1. Reese and Mandels have recently reported2 the isolation and partial purification of an inducible glucanase (mycodextranase) produced in the ...

Substrate specificity of pullulanase

Archives of Biochemistry and Biophysics, 1970
Abstract Action of pullulanase from Aerobacter aerogenes has been tested on a number of starch oligosaccharides. Hydrolysis is confined to cleavage of α-1 → 6-interchain links between oligosaccharide chains containing a minimum of two glucose units per chain.

Substrate specificity of pyroglutamylaminopeptidase

Journal of Medicinal Chemistry, 1985
Three synthetic peptides (compounds 4-6) were tested as substrates of pyroglutamylaminopeptidase. In addition, inhibition of the hydrolysis of these substrates by compounds 8 and 9 was also examined. The enzyme does not appreciably catalyze the hydrolysis of peptides with six-membered ureido rings at the amino terminus, but it tolerates well a five ...

Substrate specificity of a human-specific esterase

Analytical Biochemistry, 1973
Abstract A human species-specific esterase has been identified in tissues, cell cultures, and urine. It is the most slowly migrating (i.e., cathodal) of the esterase isoenzymes in agarose electrophoresis; it is not a choline estrase, a pseudocholine esterase, an acetyl phenylalanine-3-naphthyl esterase or N -benzoyl-arginine-3-naphthyl esterase ...

Engineering substrate specificity

Current Opinion in Structural Biology, 1991
Site-directed mutagenesis of amino acids in the active site of an enzyme can yield mutant proteins with dramatically altered substrate specificity. In the past year, several enzymes have been successfully engineered with desired changes in specificity.

Substrate specificity of Streptomyces transglutaminases

Applied Biochemistry and Biotechnology, 2007
Transglutaminase (TGase) is a multifunctional enzyme vital for many physiologic processes, such as cell differentiation, tissue regeneration, and plant pathogenicity. The acyl transfer function of the enzyme can activate primary amines and, consequently, attach them onto a peptidyl glutamine, a reaction important for various in vivo and in vitro ...

Substrate specificity of neuraminidases

The Histochemical Journal, 1973
This presentation is a brief description of neuraminidases and is mainly concerned with the substrate specificity of these enzymes. From the observed great differences in substrate specificity it is clear that we are dealing not with one enzyme called neuraminidase but with a variety of enzymes named neuraminidases.

Substrate specificity of choline kinase

Archives of Biochemistry and Biophysics, 1987
The substrate specificity of choline kinase (ATP:choline phosphotransferase, EC 2.7.1.32) from brewer's yeast has been examined using multiple analogs of choline, most of which have been reported to be a substrate of one or another choline-using system from other sources.

Substrate specificity of polyphenol oxidase

Critical Reviews in Biochemistry and Molecular Biology, 2020
The ubiquitous type-3 copper enzyme polyphenol oxidase (PPO) has found itself the subject of profound inhibitor research due to its role in fruit and vegetable browning and mammalian pigmentation. The enzyme itself has also been applied in the fields of bioremediation, biocatalysis and biosensing.
