competitive inhibition

Competitive inhibition of iron absorption by manganese and zinc in humans.

These mechanisms include , competitive inhibition or negative feedback.

Brompheniramine works by acting as an competitive inhibition of histamine H1 receptors.

Competitive inhibition of photosynthetic hydrogen production by carbon dioxide.

This is called competitive inhibition.

In competitive inhibition, the inhibitor binds to the active site, thus preventing enzyme-substrate interaction.

Anastrozole binds reversibly to the aromatase enzyme through competitive inhibition.

Competitive inhibition of hepatic sterol 27-hydroxylase by sitosterol: decreased activity in sitosterolemia.

Competitive inhibition: Some drugs may share the same P-450 specificity and thus competitively block their bio transformation.

This mechanism was suggested from studies investigating kinetic isotope effects in conjunction with competitive inhibition and active site mutagenesis.

In competitive inhibition, the inhibitor and substrate compete for the enzyme (i.e., they can not bind at the same time).

Because the inhibitor can not be driven from the enzyme by higher substrate concentration (in contrast to competitive inhibition), the apparent V changes.

PGE1 inhibits the secretion of factors that stimulate platelet aggregation by competitive inhibition .

DGLA inhibits inflammation through both competitive inhibition and direct counteraction (see above.)

Additionally, competitive inhibition using native GP900 or purified GP900 fragments reduces cell invasion.

Competitive inhibition occurs between the calcium and magnesium and the toxicants which include trace-metals and hydrogen ions .

He had an unprecedented viral infection that caused competitive inhibition of certain segments in his DNA in the process of replication.

It reverses the effects of benzodiazepines by competitive inhibition at the benzodiazepine binding site on the GABA receptor.

Competitive inhibition has been observed for ADA, where the product inosine acts at the competitive inhibitor to enzymatic activity.

In competitive inhibition, at any given moment, the enzyme may be bound to the inhibitor, the substrate, or neither, but it cannot bind both at the same time.

The RNAs are considered interfering when they attenuate the function of the parent RNA through competitive inhibition.

In competitive inhibition the maximal rate of the reaction is not changed, but higher substrate concentrations are required to reach a given maximum rate, increasing the apparent K.

The antitumor activity of fluoxymesterone appears related to reduction or competitive inhibition of prolactin receptors or estrogen receptors or production.

Dantrolene interferes with the release of calcium by binding to the ryanodine receptor and blocking the endogenous ligand ryanodine by competitive inhibition.

Dietary ω-3 and GLA counter the inflammatory effects of AA's eicosanoids in three ways - displacement, competitive inhibition and direct counteraction.
