A synthetic C4 shuttle via the β-hydroxyaspartate cycle in C3 plants
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Photorespiration is essential for photosynthesis in an oxygen-containing atmosphere. By mass flow, photorespiration is exceeded only by photosynthetic carbon assimilation.

Oxaloacetate and Malate Transport by Plant Mitochondria [PDF]
Plant Physiology, 1988 The permeability of mitochondria from pea (Pisum sativum L. var Kleine Rheinländerin) leaves, etiolated pea shoots, and potato (Solanum tuberosum) tuber for malate, oxaloacetate, and other dicarboxylates was investigated by measurement of mitochondrial swelling in isoosmolar solutions of the above mentioned metabolites.

Oxaloacetate Synthesis in Butyrivibrio fibrisolvens [PDF]
Applied and Environmental Microbiology, 1979 Phosphoenolpyruvate carboxykinase (adenosine 5′-triphosphate) was the only enzyme capable of carboxylating pyruvate or phosphoenolpyruvate that could be demonstrated in sonicated cells or cell-free extracts of a group 1 butyrivibrio.

Why Are Branched-Chain Amino Acids Increased in Starvation and Diabetes?
Nutrients, 2020 Branched-chain amino acids (BCAAs; valine, leucine, and isoleucine) are increased in starvation and diabetes mellitus. However, the pathogenesis has not been explained.

Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

FEBS Letters, EarlyView.Glutaredoxin (Grx) 3 proteins contain a thioredoxin domain and one to three class II Grx domains. These proteins play a crucial role in iron homeostasis in eukaryotic cells. In human Grx3, at least one of the two Grx domains, together with the thioredoxin domain, is essential for its function in iron metabolism.

Sub‐Units of Citrate Oxaloacetate‐Lyase [PDF]
European Journal of Biochemistry, 1971 Citrate lyase has been shown to have values for S°20,W and D°20,W of 17.6 S and 3.02 × 10−7 cm2 sec−1, respectively. Using the Svedberg equation a value of 533000 was assigned for the molecular weight of the active preparation. The meniscus depletion sedimentation equilibrium method led to a value of 550000 while the transient state method gave a value

Hepatic gluconeogenesis and regulatory mechanisms in lactating ruminants: A literature review
Animal Research and One Health, EarlyView.phosphoenolpyruvate carboxy kinase, FBP1, and glucose‐6‐phosphatase are key rate‐limiting enzymes that determine the efficiency of gluconeogenesis. The main substrate for gluconeogenesis in the liver of ruminants is propionate, which provides more than 60% of the carbon source for gluconeogenesis.

Biotechnology and Applied Biochemistry, EarlyView.ABSTRACT Actinobacillus succinogenes is a ruminal microorganism of biotechnological importance due to its capacity to produce succinic acid at high yields. Despite the scientific interest in this organism, molecular vehicles for the transfer and expression of genetic material are limited compared to the existing demand.
