isoleucine

In all other species there is an isoleucine at the position.

Isoleucine is not present in haemoglobin and must be obtained by alternative methods.

For example, rice is low in isoleucine and lysine.

It causes the body to be unable to process the amino acid isoleucine properly.

The toxicity for bacteria could be eliminated by adding isoleucine to the medium.

It is also a product of metabolism of isoleucine and valine.

These dormant forms remain viable for up to 72 hours and resume growth when isoleucine is added to the culture medium.

Isoleucine is both a glucogenic and a ketogenic amino acid.

Synthetic isoleucine was originally reported in 1905.

This mechanism of action is shared with furanomycin, an analog of isoleucine.

When isoleucine is withdrawn from an in vitro culture system, the parasite enters a dormant form.

Isoleucine can be synthesized in a multistep procedure starting from 2-bromobutane and diethylmalonate.

It is also one of two common amino acids that bear a chiral side chain, along with isoleucine.

Tiglyl-CoA is an intermediate in the metabolism of isoleucine.

With a hydrocarbon side chain, isoleucine is classified as a hydrophobic amino acid.

Without adequate biotin, the human body will be unable to fully break down isoleucine and leucine molecules.

Without biotin, leucine and isoleucine cannot be fully metabolized.

If archaea lack ilvA, what is the source of α-ketobutyrate for isoleucine biosynthesis?

A-to-I editing changes an isoleucine codon to code for a methionine residue.

This results in translation of a methionine instead of an isoleucine at the I/M site.

The resulting product of this reaction, acetolactate, eventually becomes valine, leucine, and isoleucine.

Along with leucine and isoleucine, valine is a branched-chain amino acid.

This enzyme participates in a novel pyruvate pathway for isoleucine biosynthesis.

The parasite has an absolute requirement for isoleucine - an amino acid absent from human haemoglobin.

This is probably because isoleucine and valine are highly mutable residues in TM-helices.
