释义 | BETA Examples of threoninethreonine isn’t in the Cambridge Dictionary yet. You can help! Insertion of an extra codon for threonine is a cause of dihydropteridine reductase deficiency. All other strains had a threonine at this position. The residue changes are glycine at position 82 (previously glutamic acid), threonine at position 218 (previously asparagine) and valine at position 255 (previously alanine). This is true particularly for serine and threonine, since they are generally unstable in the desert environment. Phosphorylation of serine 16 and threonine 17 in response to beta-adrenergic stimulation. Serine dehydratase can use threonine as a substrate but there was no evidence for this in our experiments. Phosphorylation is diminished if positively charged amino acids are close to the target serine/threonine. By contrast, hydrophobic or negatively charged amino acids enhance phosphorylation of serine/threonine. In addition, 3 unknown peaks, possibly peptides, were observed; these were eluted first from the acid-neutral column, appearing before threonine and serine. Effects of serine/threonine protein phosphatases on ion channels in excitable membranes. Species distantly related to rodents show little sequence conservation in this region, with a variety of different arrangements of serine/threonine residues. The most frequent amino acid whose sidechain is contacting the magnesium ion is aspartate (42 %), followed by threonine (23 %), glutamate (17 %) and serine (10 %). Glutamine increased throughout endosperm development, as did asparagine, alanine, valine, serine and threonine. Protein serine/threonine phosphatases-new avenues for cell regulation. Membrane localization of the kinase which phosphorylates p34cdc2 on threonine 14. Limk1 is predominantly expressed in neural tissues and phosphorylates serine, threonine and tyrosine residues in vitro. |
