The conformational space of 5-acetic acid hydantoin {5AAH; [2-(2,5-dioxoimidazolidin-4-yl)acetic acid]} was investigated by quantum chemical calculations performed at the DFT(B3LYP)/6-311++G(d,p) level of theory. A total of 13 conformers were located in the potential energy surface of the molecule, six of

New types of antimicrobial compounds were identified in the culture filtrate of Lactobacillus plantarum VTT E-78076. Activity was detected in the low molecular mass fraction separated by gel chromatography. This fraction totally inhibited the growth of the Gram-negative test organism

Cyclic imide-transforming activity was found to be widely distributed in bacteria, yeast and molds. This activity was not correlated with cyclic ureide-transforming activity in bacteria, but there was some correlation in yeast and molds. These two activities are probably catalyzed

Overexpression of a novel hydantoinase (hyuH) from P. aeruginosa (MCM B-887) in E. coli yielded optically pure carbamoyl amino acids. The use of optically pure carbamoyl amino acids as substrates facilitates the synthesis of non-proteinogenic amino acids. The enzyme hyuH
