## Abstract By use of a polycondensation procedure free of racemization, stereoregular polymethionines have been synthesized from C‐activated D‐methionyl‐L‐methionine and L‐methionyl‐D‐methionyl‐L‐methionine. The poly(D‐methionyl‐L‐methionine) and poly(L‐methionyl‐D‐methionyl‐L‐methionine) so prep
## Abstract Infrared spectroscopy, X‐ray diffraction, and nuclear magnetic resonance spectroscopy have been used in investigating the conformation of two stereoregular polymethionines, poly(D‐methionyl‐L‐methionine) and poly(L‐methionyl‐D‐methionyl‐L‐methionine). When dissolved in a helicogenic sol
## Abstract D‐Methionine was converted to L‐methionine in a reaction system where four enzymes were used. D‐amino acid oxidase (D‐AAO) from __Arthrobacter protophormiae__ was used for the complete conversion of D‐methionine to 2‐oxo‐4‐methylthiobutyric acid. Catalase was added to prevent 2‐oxo‐4‐me
