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 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 ...

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 ...

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.

Engineering substrate specificity
Current Opinion in Structural Biology, 1991Site-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, 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 polyphenol oxidase
Critical Reviews in Biochemistry and Molecular Biology, 2020The 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.

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 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 ...
