Two benzoyl-l-tyrosine p-nitroanilide hydrolases (BTPAases I and II) were purified from the etiolated leaves of Zea mays L. and characterized. BTPAase I was electrophoretically homogeneous and consisted of two identical subunits having a molecular weight of 53,000. The molecular weight of BTPAase II
Optimization of extraction parameters of PTP1β (protein tyrosine phosphatase 1β), inhibitory polyphenols, and anthocyanins from Zea mays L. using response surface methodology (RSM).

BACKGROUND
Protein tyrosine phosphatase expressed in insulin-sensitive tissues (such as liver, muscle, and adipose tissue) has a key role in the regulation of insulin signaling and pathway activation, making protein tyrosine phosphatase a promising target for the treatment of type 2 diabetes

Chitinase isolated from Zea mays seeds is inactivated by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) in the absence of exogenous nucleophiles. Oligomers of N-acetylglucosamine,N,N',N",N"'-tetra-N-acetylchitotetraose (GlcNAc4), and to a lesser extent, N,N',N"-tri-N-acetylchitotriose (GlcNAc3)

In a search for tRNA-processing nucleases in Zea mays an activity was found which cleaves the precursor to Escherichia coli tyrosine tRNA in the loop of the extra arm within the mature tRNA sequence. The activity (named RNase Zma) was partially purified by ion exchange and gel filtration

D-serine selectively damages renal proximal tubule cells in rats by a mechanism that is not fully understood. Recent proteomic analysis identified that D-serine elevated plasma fumarylacetoacetate hydrolase (FAH). FAH is involved in tyrosine catabolism; hence, this pathway may be involved in
Repeated exposure of adult rats to Aroclor 1254 causes brain region-specific changes in intracellular Ca2+ buffering and protein kinase C activity in the absence of changes in tyrosine hydroxylase.

Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants, some of which may be neurotoxic. In vitro studies from this laboratory indicated that noncoplanar PCBs perturbed intracellular signal transduction mechanisms including Ca2+ homeostasis, receptor-mediated inositol phosphate

Fluazifop-p-butyl (FL) is one of the most popular graminicides from arylophenoxypropionate group. These herbicides act as inhibitors of acetyl-CoA carboxylase (ACCase) that catalyzes the formation of malonyl-CoA during metabolism of lipids and/or of some secondary compounds. On the other hand

Epidemiological and laboratory animal model studies suggest that the effect of dietary fat on colon carcinogenesis depends on the amount and its type. In the present study, we investigated the modulating effect of high-fat diets rich in omega-3, omega-6 and omega-9 fatty acids on liver, colon and

We investigated the effect of dexamethasone (DEX) on tyrosine hydroxylase (TH) mRNA level, and TH activity and catecholamine levels in the adrenal medulla of the rat. DEX (1 mg/kg/day, s.c.) was administered for 2 days, and a control group was given corn oil. DEX significantly increased systolic

Plant glycine-rich RNA-binding proteins (GRRBPs) contain a glycine-rich region at the C-terminus whose structure is quite unknown. The C-terminal glycine-rich part is interposed with arginine and tyrosine (arginine/glycine/tyrosine (RGY)-rich domain). Comparative sequence analysis of forty-one

OBJECTIVE
To study the effects of pyrethroids on tyrosine hydroxylase in nigrostriatum of male rats.
METHODS
Different doses of permethrin and deltamethrin in corn oil were administered to rats by gavage for ten days, then PLC-Fluorescence detection was used to analyzed the contents of dopamine

Protein tyrosine phosphatases (PTPases) have long been thought to be activated by reductants and deactivated by oxidants, owing to the presence of a crucial sulfhydryl group in their catalytic centers. In this article, we report the purification and characterization of Reductant-Inhibited PTPase1
