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 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 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 squalene synthetase
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 198022 artificial homologues of farnesyl pyrophosphate were examined for the reactivity as substrate for squalene synthetase of pig liver microsomes. 16 of the homologues were found to be reactive to give corresponding squalene-like products. Extention of the omega-terminal of the carbon chain of farnesyl pyrophosphate is acceptable to the enzyme at least ...

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 ...

Substrate specificity of vertebrate collagenase
Biochimica et Biophysica Acta (BBA) - Enzymology, 1976Substrate specificity of purified tadpole collagenase (EC 3.4.24.3) has been studied using eleven synthetic peptides. A pentapeptide, t-butyloxycarbonylprolylalanylglycylisoleucylalanine amide, was susceptible to the action of the enzyme and an octapeptide, acetylprolylglutaminylglycylisoleucylalanylglycylglutaminylarginine ethyl ester, was proposed to
