متن کاملTertiary alcohol preferred: Hydroxylation of trans-3-methyl-L-proline with proline hydroxylases
The enzymatic synthesis of tertiary alcohols by the stereospecific oxidation of tertiary alkyl centers is a most-straightforward but challenging approach, since these positions are sterically hindered. In contrast to P450-monooxygenases, there is little known about the potential of non-heme iron(II) oxygenases to catalyze such reactions. We have studied the hydroxylation of trans-3-methyl-L-pro...
متن کاملOxidation of hydroxy-L-proline by periodate.
Some time ago Carter and Neville reported (1) that hydroxy-n-proline yields formaldehyde on oxidation with periodate. In another laboratory, this oxidation was found to produce a considerably lower yield of formaldehyde than we had obtained.’ A further study of this reaction was accordingly undertaken. Oxidation of several new samples of hydroxy-L-proline gave lower yields of formaldehyde than ...
متن کاملIdentification and characterization of trans-3-hydroxy-l-proline dehydratase and Δ1-pyrroline-2-carboxylate reductase involved in trans-3-hydroxy-l-proline metabolism of bacteria
trans-4-Hydroxy-l-proline (T4LHyp) and trans-3-hydroxy-l-proline (T3LHyp) occur mainly in collagen. A few bacteria can convert T4LHyp to α-ketoglutarate, and we previously revealed a hypothetical pathway consisting of four enzymes at the molecular level (J Biol Chem (2007) 282, 6685-6695; J Biol Chem (2012) 287, 32674-32688). Here, we first found that Azospirillum brasilense has the ability to ...
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...
