Overexpression of Phosphoserine Aminotransferase (PSAT)-Enhanced Cadmium Resistance and Accumulation in Duckweed (Lemna turionifera 5511) [PDF]
Cadmium (Cd) hampers plant growth and harms photosynthesis. Glutamate (Glu) responds to Cd stress and activates the Ca2+ signaling pathway in duckweed, emphasizing Glu’s significant role in Cd stress.

Structural Analysis of Phosphoserine Aminotransferase (Isoform 1) From Arabidopsis thaliana– the Enzyme Involved in the Phosphorylated Pathway of Serine Biosynthesis [PDF]
Phosphoserine aminotransferase (PSAT) is a pyridoxal 5′-phosphate (PLP)-dependent enzyme that catalyzes the conversion of 3-phosphohydroxypyruvate (3-PHP) to 3-phosphoserine (PSer) in an L-glutamate (Glu)-linked reversible transamination reaction.

The protective effects of phosphoserine aminotransferase 1 (PSAT1) against hepatic ischemia-reperfusion injury. [PDF]
Hepatic ischemia-reperfusion (I/R) injury is a severe clinical syndrome, causing a profound medical and socioeconomic burden worldwide. This study aimed to explore underlying biomarkers and treatment targets in the progression of hepatic I/R injury. We screened gene expression profiles of the hepatic I/R injury from the Gene Expression Omnibus (GEO ...

Phosphoserine aminotransferase deficiency: a novel disorder of the serine biosynthesis pathway. [PDF]
We present the first two identified cases of phosphoserine aminotransferase deficiency. This disorder of serine biosynthesis has been identified in two siblings who showed low concentrations of serine and glycine in plasma and cerebrospinal fluid. Clinically, the index patient presented with intractable seizures, acquired microcephaly, hypertonia, and ...

Phosphoserine Aminotransferase, the Second Step‐Catalyzing Enzyme for Serine Biosynthesis [PDF]
AbstractAs a step toward analyzing the serine biosynthetic pathway in mammals, we have studied the properties of phosphoserine aminotransferase, the second step‐catalyzing enzyme. The Km values for 3‐phosphohydroxypyruvate and L‐phosphoserine are 5 and 35 mu M, respectively, and those for glutamate and alpha‐ketoglutarate are 1.2 and 0.8 mM ...

Comparison of kinetic and enzymatic properties of intracellular phosphoserine aminotransferases from alkaliphilic and neutralophilic bacteria [PDF]
Intracellular pyridoxal 5´-phosphate (PLP) -dependent recombinant phosphoserine aminotransferases (PSATs; EC 2.6.1.52) from two alkaliphilic Bacillus strains were overproduced in Escherichia coli, purified to homogeneity and their enzymological ...

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
