Discovery of a second citric acid cycle complex [PDF]

open access: yesHeliyon, 2023
Together, Nobel Prize honoured work, mathematics, physics and the laws of nature have drawn a concept of clockwise cycling carboxylic acids in Krebs’ Citric Acid Cycle. A Citric Acid Cycle complex is defined by specific substrate, product and regulation.

Linked cycles of oxidative decarboxylation of glyoxylate as protometabolic analogs of the citric acid cycle [PDF]

open access: yesNature Communications, 2018
The citric acid cycle (TCA) is a fundamental metabolic pathway to release stored energy in living organisms. Here, the authors report two linked cycles of reactions that each oxidize glyoxylate into CO2 and generate intermediates shared with the modern ...

Abiotic origin of the citric acid cycle intermediates. [PDF]

open access: yesProc Natl Acad Sci U S A
The molecular framework for protometabolism—chemical reactions in a prebiotic environment preceding modern metabolism—has remained unknown in evolutionary biology. Mono-, di-, and tricarboxylic acids that comprise contemporary metabolism, such as the Krebs cycle, are of particular prebiotic relevance and are theorized to predate life on Earth ...

Hgt17-Adr1 Relationship in Candida albicans Citrate Utilization [PDF]

open access: yesJournal of Fungi
The fungal pathogen Candida albicans can infect diverse tissues, a reflection of its broad metabolic repertoire. The transcription factor Adr1 is required for utilization of several citric acid cycle intermediates that are found in tissue.

Citric acid cycle and the origin of MARS. [PDF]

open access: yesTrends Biochem Sci, 2013
The vertebrate multiaminoacyl tRNA synthetase complex (MARS) is an assemblage of nine aminoacyl tRNA synthetases (ARSs) and three non-synthetase scaffold proteins, aminoacyl tRNA synthetase complex-interacting multifunctional protein (AIMP)1, AIMP2, and AIMP3.

Citric Acid in Endodontics: A Review [PDF]

open access: yesJournal of Dental Materials and Techniques, 2021
Naturally occurring in citrus fruits, citric acid is categorized as a weak organic acid, which may exist both as a monohydrate or in an anhydrous form.

Changes in TCA cycle and TCA cycle-related metabolites in plasma upon citric acid administration in rats

open access: yesHeliyon, 2021
Recent studies have reported that plasma levels of tricarboxylic acid (TCA) cycle metabolites and TCA cycle-related metabolite change in patients with chronic fatigue syndrome (CFS) and in healthy humans after exercise.

FaGAPC2/FaPKc2.2 and FaPEPCK reveal differential citric acid metabolism regulation in late development of strawberry fruit

open access: yesFrontiers in Plant Science, 2023
Citric acid is the primary organic acid that affects the taste of strawberry fruit. Glycolysis supplies key substrates for the tricarboxylic acid cycle (TCA cycle).

Combined metabolomic and transcriptomic analysis reveals key components of OsCIPK17 overexpression improves drought tolerance in rice

open access: yesFrontiers in Plant Science, 2023
Oryza Sativa is one of the most important food crops in China, which is easily affected by drought during its growth and development. As a member of the calcium signaling pathway, CBL-interacting protein kinase (CIPK) plays an important role in plant ...
