Extending enzyme molecular recognition with an expanded amino acid alphabet

open access: yes, 2017
Natural enzymes are constructed from the twenty proteogenic amino acids, which may then require post-translational modification or the recruitment of coenzymes or metal ions to achieve catalytic function.

The first step into phenolic metabolism in the hornwort Anthoceros agrestis: molecular and biochemical characterization of two phenylalanine ammonia-lyase isoforms [PDF]

open access: yes, 2022
Two isoforms of phenylalanine ammonia-lyase (PAL) have been isolated as cDNA sequences from the hornwort Anthoceros agrestis. The encoded enzymes convert L-phenylalanine and to lower extents L-tyrosine and L-histidine.

Fruit respiration: putting alternative pathways into perspective

open access: yesNew Phytologist, EarlyView.
Summary Over the past century, research has significantly advanced our understanding of fruit respiration, from (eco)physiological processes to molecular mechanisms. This review focuses on the functional relevance and regulatory roles of mitochondrial alternative respiratory pathways (ARPs) during fruit growth and ripening.

Biosynthesis of caffeic acid in Escherichia coli using its endogenous hydroxylase complex

open access: yesMicrobial Cell Factories, 2012
Background Caffeic acid (3,4-dihydroxycinnamic acid) is a natural phenolic compound derived from the plant phenylpropanoid pathway. Caffeic acid and its phenethyl ester (CAPE) have attracted increasing attention for their various pharmaceutical ...

Root tip excision‐induced exodermis lignification impacts lateral root emergence in Brachypodium distachyon

open access: yesNew Phytologist, EarlyView.
Summary The mechanisms controlling lateral root emergence in monocots, particularly the role of the exodermis, are poorly understood. We investigated how natural variation in the Brachypodium distachyon stress response shapes root system architecture by modulating cell wall dynamics.

Dehydroalanine in Histidine Ammonia Lyase

open access: yesJournal of Biological Chemistry, 1969
Abstract Preparations of highly purified Pseudomonas histidine ammonia lyase were inactivated by reduction with sodium borotritide. Alanine was the only labeled material in acid hydrolysates of the dialyzed product. Its presence indicates the presence of dehydroalanine (2-aminoacrylic acid) in the enzyme.

From Aminomutases to Ammonia Lyases: A Protein Engineering Study [PDF]

open access: yesBiophysical Journal, 2014
Ammonia lyases and aminomutases are emerging as important enzymatic systems, not only in green synthetic routes to chiral amines, but also as potential target for enzyme therapeutic for treating diseases such as phenylketonuria and cancer (1). On the other hand, β-amino acids harbor many applications in their free form and as building blocks of ...

Quiescence of postharvest pathogens: a fungal inhibition process or an immune response of the unripe host fruit?

open access: yesNew Phytologist, EarlyView.
Summary Postharvest pathogens can infect fresh produce both before and after harvest, by direct or wound‐enhanced penetration, remaining quiescent until ripening. Biotrophic‐like postharvest pathogens persist beneath host cells and can remain in a state of quiescence.

Studies on lignification in wheat (Triticum aestivum var. Thatcher) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Botany at Massey University [PDF]

open access: yes, 1975
PART I Transections of the stem of Triticum were examined after staining with dyes specific for functional groups within the lignin polymer. Anatomical observations suggest that the basis for the rapid increase in the lignin content of this plant 35 to ...

Optimization of carbon and nitrogen utilization for enhanced photosynthesis, biomass and yield by coexpression of phosphoenolpyruvate carboxylase, aspartate aminotransferase and glutamine synthetase in Brassica juncea

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Coexpression of genes involved in carbon (C) and nitrogen (N) metabolism offers a promising avenue for improving crop yield. This study investigated the impact of coexpressing phosphoenolpyruvate carboxylase [ZmPEPC (P)], aspartate aminotransferase [GmAspAT (A)] and glutamine synthetase [NtGS (G)] in Brassica juncea to enhance plant yield ...
