Phosphoserine aminotransferase 1 promotes serine synthesis pathway and cardiac repair after myocardial infarction. [PDF]
Background and Purpose: The permanent loss of cardiomyocytes (CMs) following myocardial infarction (MI), coupled with the heart's limited regenerative capacity, often leads to heart failure. Phosphoserine aminotransferase 1 (PSAT1) is a protein highly expressed in the embryonic mouse heart but markedly downregulated after birth. Despite its presence in

Objective. Endoplasmic reticulum (ER) stress and hypoxia are key factors for the effective growth of malignant tumors, including glioblastoma. The phosphoserine aminotransferase 1 (PSAT1) is an ER stress-responsive enzyme responsible for serine synthesis

Protein post-translational modifications in serine synthetic pathway: functions and molecular mechanisms [PDF]
Serine is a non-essential amino acid, serving as a precursor for other amino acids, lipids, and nucleotide synthesis. Its supply is ensured by two main mechanisms: exogenous uptake and endogenous synthesis.

Strain relief at the active site of phosphoserine aminotransferase induced by radiation damage. [PDF]
AbstractThe X‐ray susceptibility of the lysine‐pyridoxal‐5′‐phosphate Schiff base in Bacillus alcalophilus phosphoserine aminotransferase has been investigated using crystallographic data collected at 100 K to 1.3 Å resolution, complemented by on‐line spectroscopic studies.

Dietary sulfur amino acid restriction improves glucose homeostasis through hepatic de novo serine synthesis [PDF]
Dietary sulfur amino acid restriction (SAAR) improves whole-body glucose homeostasis, elevates liver insulin action, and lowers liver triglycerides. These adaptations are associated with an increased expression of hepatic de novo serine synthesis enzymes,

Over-Expression of Phosphoserine Aminotransferase-Encoding Gene (AtPSAT1) Prompts Starch Accumulation in L. turionifera under Nitrogen Starvation. [PDF]
It has been demonstrated that the phosphorylation pathway of L-serine (Ser) biosynthesis (PPSB) is very important in plant growth and development, but whether and how PPSB affects nitrogen metabolism and starch accumulation has not been fully elucidated.

ATF3 promotes the serine synthesis pathway and tumor growth under dietary serine restriction
Summary: The serine synthesis pathway (SSP) involving metabolic enzymes phosphoglycerate dehydrogenase (PHGDH), phosphoserine aminotransferase 1 (PSAT1), and phosphoserine phosphatase (PSPH) drives intracellular serine biosynthesis and is indispensable ...
