Proline (symbol Pro or P) [4] ... In plants, proline accumulation is a common physiological response to various stresses but is also part of the developmental program ...
Hydroxyproline and proline play key roles for collagen stability. [4] They permit the sharp twisting of the collagen helix. [5] In the canonical collagen Xaa-Yaa-Gly triad (where Xaa and Yaa are any amino acid), a proline occupying the Yaa position is hydroxylated to give a Xaa-Hyp-Gly sequence.
Prolamins are a group of plant storage proteins having a high proline amino acid content. They are found in plants, mainly in the seeds of cereal grains such as wheat , barley , rye , corn , sorghum , and oats . They are characterised by a high glutamine and proline content, and have poor solubility in water. They solubilise best in strong ...
In some plants, pipecolic acid act as a defense compound against microorganisms. [1] Because of its limited presence, pipecolic acid is considered a secondary metabolite. Structural formula for the amino acid proline, that in all living beings is a building block in proteins. Because of its universal presence, proline is considered a primary ...
The α-ketoglutarate family of amino acid synthesis (synthesis of glutamate, glutamine, proline and arginine) begins with α-ketoglutarate, an intermediate in the Citric Acid Cycle. The concentration of α-ketoglutarate is dependent on the activity and metabolism within the cell along with the regulation of enzymatic activity.
These include an amino acid (protein) called proline and tiny sugars called trehalose. The cryoprotectants work in a number of ways to protect cells, membranes, and delicate proteins from being ...
In protein, hydroxyproline is incorporated into protein by hydroxylation of proline. Pipecolic acid, a heavier analog of proline, is found in efrapeptin. Sarcosine is a N-methylized glycine so its methyl group is used in many biochemical reactions. Azetidine-2-carboxylic acid, which is a smaller homolog of proline in plants.
They are implicated in various aspects of plant growth and development, including root elongation, somatic embryogenesis, hormone responses, xylem differentiation, pollen tube growth and guidance, programmed cell death, cell expansion, salt tolerance, host-pathogen interactions, and cellular signaling.
