Cis-4-Hydroxy-D-proline (2584-71-6) video
Cis-4-Hydroxy-D-proline belongs to the class of organic compounds known as proline and derivatives. Proline and derivatives are compounds containing proline or a derivative thereof resulting from a reaction of proline at the amino group or the carboxyl group, or from the replacement of any hydrogen of glycine by a heteroatom. cis-4-Hydroxy-D-proline is a substrate that may be used to study the specificity and kinetics of D-alanine dehydrogenase.

Epimerization of trans-4-hydroxy-l-proline to cis-4-hydroxy-d-proline during acid hydrolysis of collagen:
- Trans-4-Hydroxy-l-proline is epimerized to cis-4-hydroxy-d-proline under the conditions generally used for the hydrolysis of proteins for analyses of amino acids.
- The cis epimer elutes from a column of UR-30 resin on a Beckman amino acid analyzer at the same time as threonine and hence would be undetected.
- About 8% of the trans-4-hydroxy-l-proline in collagen can be epimerized to cis-4-hydroxy-d-proline in the hydrolysis of collagen with 6 N HCl at 110° for 72 hr.

Epimerization of trans-4-hydroxy-l-proline to cis-4-hydroxy-d-proline during acid hydrolysis of collagen
A procedure is described whereby the primary amino acids in hydrolyzates are deaminated with nitrous acid and removed so that the amounts of trans-4-hydroxyproline, cis-4-hydroxyproline, and proline can be determined without changing the temperature of the column of UR-30 resin on the Beckman amino acid analyzer.

Characterization of cis-4-hydroxy-D-proline dehydrogenase from Sinorhizobium meliloti
The hypO gene from Sinorhizobium meliloti, located within the trans-4-hydroxy-L-proline metabolic gene cluster, was first successfully expressed in the host Pseudomonas putida. Purified HypO protein functioned as a FAD-containing cis-4-hydroxy-D-proline dehydrogenase with a homomeric structure.
