3,4-脱氢-DL-脯氨酸文献

Many amino acid substitutions in a hypoxia-inducible transcription factor (HIF)-1alpha-like peptide cause only minor changes in its hydroxylation by the HIF prolyl 4-hydroxylases: substitution of 3,4-dehydroproline or azetidine-2-carboxylic acid for the proline leads to a high rate of uncoupled 2-oxoglutarate decarboxylation.

J. Biol. Chem. 279(53) , 55051-9, (2004)

Three human prolyl 4-hydroxylases (P4Hs) regulate the hypoxia-inducible transcription factors (HIFs) by hydroxylating a Leu-Xaa-Xaa-Leu-Ala-Pro motif. We report here that the two leucines in the Leu-G...

Overexpression of decorin by rat arterial smooth muscle cells enhances contraction of type I collagen in vitro.

Arterioscler. Thromb. Vasc. Biol. 24(1) , 67-72, (2004)

Overexpression of decorin reduces neointimal thickening in balloon-injured carotid arteries of rats by decreasing the volume of neointimal extracellular matrix (ECM). We examined the hypothesis that d...

Enhanced and feedback-resistant gamma-glutamyl kinase activity of an Escherichia coli transformant carrying a mutated proB gene of Streptococcus thermophilus.

FEMS Microbiol. Lett. 182(1) , 143-7, (2000)

We used a PCR-based method to generate a single base pair mutation in the proB gene of Streptococcus thermophilus, which replaced an aspartic acid with a glycine residue at position 192 of the first p...
