DOCUMENT TYPE: Patent CA Section: 16 (Fermentations) L-phenylalanine [63-91-2] was produced from 5-benzylhydantoin [3530-82-3] catalyzed by hydrolase of Flavobacterium aminogenes. Thus, 10 g cells of F. aminogenes AJ-3912 were added to 200 ml of phosphate buffer (pH 8.0) contg. 2 g DL-phenylalanine hydantoin and reacted at 43.degree. for 27 h. The reaction supernatant was ultrafiltered through a membrane of mol.There are some commonly used reagents with their cas registry numbers 63-91-2 and 3530-82-3 in this article. wt. of 10,000, the filtrate was concd. to 30 ml, and crystd. by cooling to yield 1.41 g L-phenylalanine. .

Stabilization of folded conformation in hydantoins and thiohydantoins

Stabilization of folded conformation in hydantoins and thiohydantoins.Some chemicals with cas registry numbers like 2233-09-2 and 3530-82-3 are also used. Attia, Ibrahim; Siemion, Ignacy Z. (Inst. Chem., Univ. Wroclaw, Wroclaw, Pol.). Rocz. Chem., 50(12), 2063-70 (English) 1976. CODEN: ROCHAC. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 34 On the basis of NMR, the folded conformation of I (R, R1, X given: CH2Ph, H, O; CH2Ph, Ph, O (II); indolylmethyl, H, O) is the more stable, although it is weaker than that for cyclic dipeptides. The dependence of folded, unfolded conformation equil. consts. on temp. was calcd. by measurements of coupling consts.
