Photosynthesis of amino acids [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - General Subjects, 1964
Abstract Methods have been developed for performing dual tracer experiments with 15 N and 14 C on the photosynthesis and biosynthesis of amino acids in Chlorella pyrenoidosa . These methods involved the development of apparatus for maintaining algae in a condition of steady-state photosynthesis, including amino acid synthesis, and of adding ...

Synthesis of potentially bioactive PABA-related N-(aminoalkyl)lactamic amino acids and esters via selective SNAr reactions [PDF]

open access: yes, 2015
Potentially bioactive N-(aminoalkyl)lactamic amino acids and esters were synthesized in satisfactory to good yields by SNAr reactions of aromatic acids with N-(3-aminopropyl)lactams followed by esterification with tertiary amino alcohols.

Amino Acids and Inherited Amino Acid-Related Disorders [PDF]

open access: yesJournal of Nutrition and Metabolism, 2018
Amino acids perform multiple essential physiological roles in humans, and accordingly, their importance to health has been the subject of extensive attention. In this special issue of the Journal of Nutrition and Metabolism, we focus on the various inborn errors of amino acid metabolism, their diagnostic challenges, new treatment approaches, and recent

Variants of the industrially relevant protease KP-43 with suppressed activity under alkaline conditions developed using expanded genetic codes

open access: yesBiochemistry and Biophysics Reports, 2019
In the present study, we attempted to control the pH profile of the catalytic activity of the industrially relevant alkaline protease KP-43, by incorporating 3-nitro-l-tyrosine and 3-chloro-l-tyrosine at and near the catalytic site. Thirty KP-43 variants
