Substrate Specificity of Mycodextranase
Nature, 1966MYCODEXTRAN (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 pyroglutamylaminopeptidase
Journal of Medicinal Chemistry, 1985Three 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 caeruloplasmin. Phenylalkylamine substrates
Biochemical Pharmacology, 1974Abstract Several phenylalkylamines have been examined as substrates for the copper-containing oxidase caeruloplasmin and it has been shown that the compounds most readily oxidized by this enzyme are those which contain a 3,4-dioxygenation pattern in the aromatic ring.

Substrate specificity of a human-specific esterase
Analytical Biochemistry, 1973Abstract 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 ...

Substrate specificity of neuraminidases
The Histochemical Journal, 1973This 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 Streptomyces transglutaminases
Applied Biochemistry and Biotechnology, 2007Transglutaminase (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 strictosidine synthase
Bioorganic & Medicinal Chemistry Letters, 2006Strictosidine synthase catalyzes a Pictet-Spengler reaction in the first step in the biosynthesis of terpene indole alkaloids to generate strictosidine. The substrate requirements for strictosidine synthase are systematically and quantitatively examined and the enzymatically generated compounds are processed by the second enzyme in this biosynthetic ...

Substrate specificity of adenovirus protease
Virus Research, 2002The adenovirus protease, adenain is functionally required for virion uncoating and virion maturation and release from the infected cell. In addition to hydrolysis of precursor proteins at specific consensus sites, adenain has also been observed to cleave viral proteins at other sites. Here we re-examine the sequences in the consensus sites and also the

The substrate specificity of tocopherol cyclase
Bioorganic & Medicinal Chemistry, 1996The substrate specificity of the enzyme tocopherol cyclase from the blue-green algae Anabaena variabilis (Cyanobacteria) was investigated with 11 substrate analogues revealing the significance of three major recognition sites: (i) the OH group at C(1) of the hydroquinone, (ii) the (E) configuration of the double bond, and (iii) the length of the ...
