Hydroxylation of Proline in Vitro
Nature, 1959WHILE carrying out a study of hydroxyproline synthesis in biological media, by hydroxylation of proline or peptides containing proline, we have also investigated the possibility of hydroxylation of pyrrolidine ring in vitro. We commenced our study by ascertaining1,2,3 whether or not cortisone inhibited the formation of free hydroxyproline in animal ...

Molecular Structure of Proline
Chemistry – A European Journal, 2004AbstractThe molecular structures of the two lowest‐energy conformers of proline, Pro‐I and Pro‐II, have been characterized by ab initio electronic structure computations. An extensive MP2/6‐31G* quartic force field for Pro‐I, containing 62 835 unique elements in the internal coordinate space, was computed to account for anharmonic vibrational effects ...

Prolinates as Secondary Amines in Aminocarbonylation: Synthesis of NAcylated Prolinates
Letters in Organic Chemistry, 2006Methyl prolinate and benzyl prolinate were used as secondary amine nucleophiles in palladium catalysed aminocarbonylation of iodo-aromatics and iodo-alkenes. A mixture of 2-oxo-carboxamide and carboxamide type derivatives or pure carboxamides can be obtained by using iodo-benzene or iodo-alkenes as substrates, respectively.

Penultimate Proline in Neuropeptides
Analytical Chemistry, 2015A recent ion mobility spectrometry-mass spectrometry (IMS-MS) study revealed that tryptic peptide ions containing a proline residue at the second position from the N-terminus (i.e., penultimate proline) frequently adopt multiple conformations, owing to the cis-trans isomerization of Xaa(1)-Pro(2) peptide bonds [J. Am. Soc. Mass Spectrom. 2015, 26, 444].

Publisher Summary This chapter focuses on proline racemase. Two methods are available for determination of proline racemase activity. One of these makes use of the fact that the optical rotation of L-proline is sufficiently great, [α]D —86°, that its enzymatic conversion to the racemic mixture may be followed in a Model D Beckman polarimetric unit ...
