Maximizing efficiency of rumen microbial protein production. [PDF]

, 2015
Rumen microbes produce cellular protein inefficiently partly because they do not direct all ATP toward growth. They direct some ATP toward maintenance functions, as long-recognized, but they also direct ATP toward reserve carbohydrate synthesis and ...

Lactylation in cancer biology: Unlocking new avenues for research and therapy

Cancer Communications, EarlyView.
Abstract Lactylation, a newly identified post‐translational modification, plays a multifaceted role in cancer biology by integrating epigenetic and non‐epigenetic mechanisms. This review summarizes the latest research progress on lactylation, including its functions in epigenetic regulation and its broader impact on cellular processes.

Differential gene expression in Chorthippus parallelus (Zetterstedt, 1821) (Orthoptera: Acrididae: Gomphocerinae) induced by Wolbachia infection

Insect Science, EarlyView.
Distinct lineages of the grasshopper Chorthippus parallelus (Orthoptera: Acrididae) form a well‐known hybrid zone (HZ) in the Pyrenees mountain range; the Iberian endemism C. p. erythropus (Cpe) and the subspecies C. p. parallelus, (Cpp) widely distributed throughout the rest of Europe. Both subspecies differ in diverse traits, including the strains of

The PEP—pyruvate—oxaloacetate node as the switch point for carbon flux distribution in bacteria: We dedicate this paper to Rudolf K. Thauer, Director of the Max-Planck-Institute for Terrestrial Microbiology in Marburg, Germany, on the occasion of his 65th birthday [PDF]

, 2017
In many organisms, metabolite interconversion at the phosphoenolpyruvate (PEP)-pyruvate-oxaloacetate node involves a structurally entangled set of reactions that interconnects the major pathways of carbon metabolism and thus, is responsible for the ...

Roles of Asp75, Asp78, and Glu83 of GTP-dependent Phosphoenolpyruvate Carboxykinase from Mycobacterium smegmatis [PDF]

Journal of Biological Chemistry, 2006
The roles of Asp(75), Asp(78), and Glu(83) of the (75)DPSDVARVE(83) element of Mycobacterium smegmatis GTP-dependent phosphoenolpyruvate (PEP) carboxykinase (GTP-PEPCK) were investigated. Asp(78) and Glu(83) are fully conserved in GTP-PEP-CKs. The human PEPCK crystal structure suggests that Asp(78) influences Tyr(220); Tyr(220) helps to position bound ...

Biochemical characterization of phosphoenolpyruvate carboxykinases from multiple species of brown algae

Journal of Phycology, EarlyView.
Abstract Phosphoenolpyruvate carboxykinase (PEPCK) is involved in the conversion of phosphoenolpyruvate (PEP) to oxaloacetate (OAA). In addition to playing a role in gluconeogenesis in various organisms, PEPCK also functions in the C4 cycle to concentrate CO2 for photosynthesis in some C4 plants.
