The work described in this paper, and its companion paper (Wu, R., Latham, J. A., Chen, D., Farelli, J., Zhao, H., Matthews, K. Allen, K. N., and Dunaway-Mariano, D. (2014) Structure and Catalysis in the Escherichia coli Hotdog-fold Thioesterase Paralogs YdiI and YbdB. Biochemistry, DOI: 10.1021/bi500334v), focuses on the evolution of a pair of paralogous hotdog-fold superfamily thioesterases o...
The assimilation of one-carbon (C1) compounds, such as methanol, by serine cycle methylotrophs requires the continuous regeneration of glyoxylate. Instead of the glyoxylate cycle, this process is achieved by a not yet established pathway where CoA thioesters are known to play a key role. We applied state-of-the-art metabolomics and (13)C metabolomics strategies to demonstrate how glyoxylate is ...
Biomimetic N-acetylcysteamine thioesters are essential for the study of polyketide synthases, non-ribosomal peptide synthetases and fatty acid synthases. The chemistry their preparation is, however, limited by specific functionalization susceptibility to undesired side reactions. Here we report a method rapid (SNAC) 7-hydroxy-2-enethioates, which suitable various enzymatic domains megasynthase ...
A model for the origin of biochemistry at an alkaline hydrothermal vent has been developed that focuses on the acetyl-CoA (Wood-Ljungdahl) pathway of CO2 fixation and central intermediary metabolism leading to the synthesis of the constituents of purines and pyrimidines. The idea that acetogenesis and methanogenesis were the ancestral forms of energy metabolism among the first free-living eubac...
