The Synthesis of γ-Alkylamides of
Bulletin of the Chemical Society of Japan, 1966 Abstract l-Theanine, a principal component of flavors contained in green teas, and its homologs have been synthesized by the reactions of several metallic salts of l-pyrrolidonecarboxylic acid with primary alkylamines. Hitherto, γ-alkylamides of l-glutamic acid had been prepared in low yields by the reactions of l-pyrrolidonecarboxylic ...

Chemical Synthesis and the Stability of Theanine
, 2011 A chemical synthesis procedure for theanine from L-pyrrolidonecarboxylic acid (L-PCA) and ethylamine was modified. L-PCA was allowed to react with excess anhydrous ethylamine (>99%) to produce theanine at 35°C for 10 days.

The formation of pyrrolid-2-one-5-carboxylic acid at the N-terminus of immunoglobulin G heavy chain
, 1972 We propose that pyrrolid-2-one-5-carboxyl-tRNA is not involved in the initiation of protein synthesis in eukaryotic cells and that the <i>N</i>-terminal pyrrolid-2-one-5-carboxylic acid group of an IgG (immunoglobulin G) (that secreted by the

Molecular characterisation of recombinant human pyroglutamyl peptidase (type I) [PDF]
, 2005 Pyroglutamyl Peptidase I (PAP1, EC 3.4.19.3) hydrolytically cleaves pyroglutamic acid (pGlu) from the N-terminal of most pGlu-peptides. In higher organisms Thyrothropin Releasing Hormone is a notable biologically active substrate of PAP1. The sequence of
