A methylaspartate cycle in haloarchaea

, 2011
Access to novel ecological niches often requires adaptation of metabolic pathways to cope with new environments. For conversion to cellular building blocks, many substrates enter central carbon metabolism via acetyl-coenzyme A (acetyl-CoA).

The Role of Reticulate Evolution in Creating Innovation and Complexity

International Journal of Evolutionary Biology, Volume 2012, Issue 1, 2012., 2012
Reticulate evolution encompasses processes that conflict with traditional Tree of Life efforts. These processes, horizontal gene transfer (HGT), gene and whole‐genome duplications through allopolyploidization, are some of the main driving forces for generating innovation and complexity. HGT has a profound impact on prokaryotic and eukaryotic evolution.

Nitric oxide delays the postharvest nutritional quality decline of “Golden Hook” beans

Food Frontiers, Volume 5, Issue 2, Page 636-655, March 2024.
NO treatment can enhance the defense ability of “Golden Hook” beans by enhancing the expression of resistance gene and promoting the expression of jasmonic acid defense pathway. NO also induced the biosynthesis of flavonoids and the accumulation of related metabolites by regulating the expression of antioxidant enzyme genes, thus enhancing its ...

Biocatalytic Enantioselective Hydroaminations for Production of N-Cycloalkyl-Substituted L-Aspartic Acids Using Two C-N Lyases [PDF]

, 2019
N‐cycloalkyl‐substituted amino acids have wide‐ranging applications in pharma‐ and nutraceutical fields. Here we report the asymmetric synthesis of various N‐cycloalkyl‐substituted L‐aspartic acids using ethylenediamine‐N,N'‐disuccinic acid lyase (EDDS ...

Malate Synthase and β-Methylmalyl Coenzyme A Lyase Reactions in the Methylaspartate Cycle in Haloarcula hispanica

, 2017
Haloarchaea are extremely halophilic heterotrophic microorganisms belonging to the class Halobacteria (Euryarchaeota). Almost half of the haloarchaea possesses the genes coding for enzymes of the methylaspartate cycle, a recently discovered anaplerotic ...

Mechanistic studies of the enzyme 3-methylaspartate ammonia-lyase

, 1989
3-Methylaspartate ammonia-lyase (E.C. 4.3.1.2), catalyses the reversible elimination of ammonia from methylaspartic acid. The enzyme from Clostridium tetanomorphum has been purified to homogeneity in three stages using a new method; acetone fractionation
