Substrate specificity of pullulanase
Archives of Biochemistry and Biophysics, 1970Abstract 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, 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 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 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 choline kinase
Archives of Biochemistry and Biophysics, 1987The 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 specificities of tobacco chitinases
The Plant Journal, 1998Ten tobacco chitinases (1,4-N-acetyl-beta-D-glucosaminide glycanhydrolase, EC 3.2.1.14) were purified from tobacco leaves hypersensitively reacting to tobacco mosaic virus. The 10 enzymes, which belong to five distinct structural classes of plant chitinases, were incubated with several potential substrates such as chitin, a beta-1,4 N-acetyl-D ...

Substrate specificity for pancreatic amylase
Gastroenterologia Japonica, 1978Substrates commonly used for the determination of amylase activity include potato starch, corn starch and dye-labeled starch. Determination of the amylase activity of serum using these different starches has shown that the measured value varies depending upon the ratio of isoamylases present, namely between pancreatic amylase (P-type) and salivary ...

Substrate specificity of ascorbate oxidase
Biochemical and Biophysical Research Communications, 1976Abstract Ascorbate oxidase oxidizes leuco 2, 6-dichloroindophenol to the blue quinoid dye and produces spectral changes in the UV spectra of certain substituted polyhydric and amino phenols at pH 5.7. The new peaks produced by the addition of enzyme to the dichlorohydroquinones (2,5 and 2,6) and hydroxyhydroquinone correspond to the respective p ...
