	Proline - Wikipedia, the free encyclopedia
		It is therefore not an amino acid although it is closely related, strictly speaking proline is an imino acid.
		Proline and its derivatives are often used as asymmetric catalysts in organic reactions.
		The CBS reduction or proline catalysed aldol condensation are prominent examples.

	Encyclopedia: Proline
		Proline is a nonessential amino acid, which means that it is manufactured from other amino acids in the liver; it does not have to be obtained directly through the diet.
		Proline is different from other amino acids in that it has a secondary amino group and contains a pyrrole ring, such as found in hemoglobin and the cytochromes.
		Proline is incorporated within a growing protein chain at the ribosome and is then hydroxylated into hydroxyproline as the growing peptide chains are still attached to the ribosome along with rough, endoplasmic reticulum.

	Amino Acids - Proline
		When proline is in a peptide bond, it does not have a hydrogen on the α amino group, so it cannot donate a hydrogen bond to stabilize an α helix or a β sheet.
		When proline is found in an α helix, the helix will have a slight bend due to the lack of the hydrogen bond.
		Proline is often found at the end of α helix or in turns or loops.

	Main pathway of proline synthesis in higher plants - Proline, ornithine and arginine metabolism - HORT640 - Metabolic ...
		The GK of the bifunctional P5CS of Vigna is inhibited by proline (50% inhibition with 6 mM proline) (Hu et al, 1992).
		Savoure et al (1997) suggest that the expression of the proline biosynthetic genes are dependent upon at least two signal transduction cascades; one triggered by exogenously applied ABA in the absence of stress, and the other triggered by cold and osmotic stress independently of exogenously applied ABA.
		In this scheme, proline produced from P5C in an "effector" tissue is transported via the phloem to a "target" tissue characterized by a high energy requirement, where proline degradation generates reducing equivalents needed to drive TCA cycle activity.

		Proline is an amino acid found primarily in meat, and synthesized in the body from Glutamate in the tricarboxylic acid cycle, and Ornithine in the urea cycle.
		Proline is necessary to support DNA and protein synthesis, and low levels may impair proper protein synthesis.
		Proline is important for wound healing, and decreases in protein synthesis have been noted in burn and traumatized patients.

	AllRefer.com - proline (Biochemistry) - Encyclopedia
		It is not essential to the human diet, since it can be synthesized in the body from glutamic acid.
		This is significant because when the amino acid is incorporated into protein, its peculiar structure leads to sharp bends, or kinks, in the peptide chain, thus figuring prominently in the determination of the protein's shape.
		Proline and its derivate hydroxyproline, make up some 21% of the amino-acid residues found in collagen, the fibrous protein of connective tissue.

		In proteins, proline can act as a structural disruptor for (α) helices (additional info and facts about α) helices), and as a turning point in β sheets (additional info and facts about β sheets).
		Sequences of proline and 1-Aminoisobutyric acid (Aib (additional info and facts about Aib)) form a helical turn structure.
		It does not have a hydrogen on the amide group and can therefore not act as a hydrogen bond (A chemical bond consisting of a hydrogen atom between two electronegative atoms (e.g., oxygen or nitrogen) with one side be a covalent bond and the other being an ionic bond) donor.

	Pathway of proline oxidation - Proline, ornithine and arginine metabolism - HORT640 - Metabolic Plant Physiology - ...
		Proline is oxidized to P5C by proline dehydrogenase [EC 1.5.99.8] and the resulting P5C is further oxidized to glutamate by P5C dehydrogenase (oxidoreductase) [EC 1.5.1.12].
		A cDNA encoding proline dehydrogenase (PDH) has recently been cloned from Arabidopsis and has been shown to be induced by proline under non-stressed conditions, but strongly repressed in response to osmotic stress (Kiyosue et al, 1996).
		For a recent discussion of the regulation of proline synthesis, degradation and transport in plants in relation to water deficits, see Taylor (1996).
