Substrate specificities of tobacco chitinases

The Plant Journal, 1998
Ten 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, 1978
Substrates 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, 1980
22 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, 1976
Abstract 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, 1976
Substrate 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

Substrate specificity of pancreatic lipase

Biochimica et Biophysica Acta (BBA) - Enzymology, 1968
Abstract 1. 1. The hydrolysis of esters of oleic acid by pancreatic lipase (glycerol-ester hydrolase, EC 3.1.1.3) depends on the nature of the alcohol. Two factors appear to influence the speed of the reaction: an inductive effect, and steric hindrance. 2. 2.

Substrate specificity of strictosidine synthase

Bioorganic & Medicinal Chemistry Letters, 2006
Strictosidine 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 muscle aldolase

Biochimica et Biophysica Acta, 1954
A study of the substrate specificity of rabbit muscle aldolase led to the following observations. 1. 1. Both the d and l isomers of glyceraldehyde-3-phosphate can be condensed with dihydroxylacetone phospahte, but the former appears to react much more rapidly than the latter. 2. 2. Tagatose-i, 6-diphosphate, which possesses a cis configuration

Substrate specificity of adenovirus protease

Virus Research, 2002
The 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
