The expression of cytochrome P450 isoenzymes (subfamilies) CYP1A, CYP2B, CYP2C, CYP3A and CYP4A in the histologically normal cervix was explored using a panel of polyclonal antibodies. There was variation in the intensity of immunohistochemical reaction between the isoenzymes and...

Synthetic oligonucleotides were used to amplify phospholipase A(2) (PLA(2)) gene by RT-PCR from total RNA of snake Agkistrodon acutus venom gland. The PCR products were subcloned and positive clones were screened with acidic PLA(2) gene from Agkistrodon halys Pallas....

An Inducible Glutathione S-Transferase in Soybean Hypocotyl Is Localized in the Apoplast.

Plant physiology

PMID: 12226439
Plant Physiol. 1996 Nov;112(3):1185-1190. doi: 10.1104/pp.112.3.1185.

Glutathione S-transferases (GSTs) with additional activities as fatty acid hydroperoxidases were investigated in soybean (Glycine max L.) hypocotyls. Aside from the GSTs present in total soluble tissue extracts, enzyme activities and distinct immunoreactive GST polypeptides were also detected in...

Immunopurification and Immunocharacterization of the Glucosinolate Biosynthetic Enzyme Thiohydroximate S-Glucosyltransferase.

Plant physiology

GrootWassink J, Reed DW, Kolenovsky AD.
PMID: 12232212
Plant Physiol. 1994 May;105(1):425-433. doi: 10.1104/pp.105.1.425.

Preparing homogeneous UDP-glucose:thiohydroximate S-glucosyltransferase (S-GT), the penultimate biosynthetic enzyme of glucosinolates, by standard chromatographic methods has yielded too little protein for adequate purity evaluation, identity verification, and structural analysis. The low yields were apparently due to low abundance in...

Comparative Studies on Ferredoxin-NADP+ Oxidoreductase Isoenzymes Derived from Different Organs by Antibodies Specific for the Radish Root- and Leaf-Enzymes.

Plant physiology

Morigasaki S, Jin T, Wada K.
PMID: 12231952
Plant Physiol. 1993 Oct;103(2):435-440. doi: 10.1104/pp.103.2.435.

Determination of the prosthetic group and titration of sulfhydryl group of ferredoxin-NADP+ oxidoreductase (FNR) from roots of radish (Raphanus sativus var acanthiformis cv Miyashige) confirmed its similarity to leaf-FNR. Antisera directed against radish root-FNR and leaf-FNR distinguished the enzyme...

Effects of Elevated Cytosolic Glutathione Reductase Activity on the Cellular Glutathione Pool and Photosynthesis in Leaves under Normal and Stress Conditions.

Plant physiology

Foyer C, Lelandais M, Galap C, Kunert KJ.
PMID: 16668524
Plant Physiol. 1991 Nov;97(3):863-72. doi: 10.1104/pp.97.3.863.

Tobacco (Nicotiana tabacum var Samsun) was transformed using the bacterial gor gene coding for the enzyme glutathione reductase. Transgenic plants were selected by their kanamycin resistence and expression of the bacterial gor gene. After separation by isoelectric focusing techniques,...

The cloning, genetic mapping, and expression of the constitutive sucrose synthase locus of maize.

Proceedings of the National Academy of Sciences of the United States of America

McCarty DR, Shaw JR, Hannah LC.
PMID: 16593784
Proc Natl Acad Sci U S A. 1986 Dec;83(23):9099-103. doi: 10.1073/pnas.83.23.9099.

Two differentially expressed genes encode isoenzymes of sucrose synthase in Zea mays. A clone of the shrunken 1 (Sh1) locus, the structural gene for the major endosperm form of sucrose synthase, was used to isolate a genomic clone of...

Specific peroxidase isoenzymes are correlated with organogenesis.

Plant physiology

PMID: 16665414
Plant Physiol. 1987 May;84(1):99-105. doi: 10.1104/pp.84.1.99.

We have examined isoperoxidase patterns obtained from buffer-, salt-, and enzyme-extractable fractions and correlated them with histological changes in tobacco (Nicotiana tabacum L., cv Wisc. 38) ;epidermal' explants induced to produce either callus, vegetative buds, or floral buds. By...

Isolation and characterization of the cytosolic and chloroplastic 3-phosphoglycerate kinase from spinach leaves.
