Free amino acids in the environment of the developing embryo (Dicotyledonous plants)

open access: yesActa Societatis Botanicorum Poloniae, 2015
The analyses of the central vacule sap in ovules of Aesculus hybrida D.C. and A. hippocastanum L. (generally during the exponential phase of the embryo growth) for free amino acids have been carried out.

Amino acid profile of eighteen isolates of different edible macrofungal species

open access: yesJournal of Horticultural Sciences, 2020
Edible mushrooms from India (18 isolates belonging to 4 species) were profiled for protein, free and bound amino acids (AA). The protein content (range of 9.5-32.6%) was highest in Pleurotus cintrinopileatus and P. sajor-caju; free AA (range of 11.6-73.1

Study on the Free Amino Acids in Plant 1. Free Amino Acids in Grasses.

open access: yesEiyo To Shokuryo, 1955
野草の遊離アミノ酸の分布をペーバークロマトグラフ法によつて調べ, エゾヨモギ葉で18種, 同茎で15種, クサソテツで12種, キスゲで13種, シロツメクサ葉で17種, 同茎で11種, フキノトオで19種, キスゲで13種のアミノ酸の存在を認めた。葉と茎に分けた場合, 葉に確認されるアミノ酸の種類が多い。量的な差としては葉部にセリン, スレオニンのオキシアミノ酸が多いことを認めた。本研究についてお協力を頂いた化学教室渡部俊夫助教授に深く感謝する。

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Free Amino Acids Analysis in the Venom of the Social Wasp Polistes lanio Under Different Forms of Preservation

open access: yesOrbital: The Electronic Journal of Chemistry, 2018
Venoms of social wasps have in their composition proteins, peptides, among others and several of these compounds were evaluated for their function in the venom, however, there is still no study of the quantification of free amino acids of venom of ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

On the amino acids in the urine of dairy cows fed urea as the sole or partial source of nitrogen

open access: yesAgricultural and Food Science, 1977
The urinary amino acids in free and bound form were determined quantitatively in dairy cows fed urea and ammonium nitrogen as the sole (0-cows) or partial (ULP-cows) source of nitrogen. For comparison, amino acid determinations were performed also on the

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
