متن کاملEpimerization of trans-4-hydroxy-L-proline to cis-4-hydroxy-D-proline during acid hydrolysis of collagen.
1. trans-4-Hydroxy-r,-proline is epimerized to &+hydroxy-n-proline under the conditions generally used for the hydrolysis of proteins for analyses of amino acids. 2. 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. 3. About 8% of the trans-4-hydroxy-L-proline in collagen can be epimerized to c&4-hydr...
متن کاملThe biosynthesis of cis-4-hydroxy-L-proline in sandal (Santalum album L.).
Two isomers of hydroxyproline are present in sandal leaves (Santalum album L.), cis-4-hydroxy-Lproline in the free state (Radhakrishnan & Giri, 1954) and bound trans-4-hydroxy-L-proline, which forms a minor proportion (4%) of total hydroxyproline (Kuttan & Radhakrishnan, 1969). Bound trans-4-hydroxy-L-proline in plants (Lamport, 1965) is presumably synthesized by a mechanism similar to that in ...
متن کاملStudies on bound trans-4-hydroxy-L-proline in sandal (Santalum album L.).
1. trans-4-Hydroxy-l-proline was found to occur in the bound state in the leaves of sandal (Santalum album L.), in which large amounts of free cis-4-hydroxy-l-proline are also present. 2. Bound trans-4-hydroxy-l-proline was present, associated mainly with a ;wall' fraction and a ;soluble' fraction roughly in equal proportions. 3. Bound proline is present only in small amounts in the ;soluble' f...
متن کاملProcess optimization for enhancing production of cis-4-hydroxy-l-proline by engineered Escherichia coli
BACKGROUND Understanding the bioprocess limitations is critical for the efficient design of biocatalysts to facilitate process feasibility and improve process economics. In this study, a proline hydroxylation process with recombinant Escherichia coli expressing L-proline cis-4-hydroxylase (SmP4H) was investigated. The factors that influencing the metabolism of microbial hosts and process econom...
