Federal government websites often end in. The site is secure. Glyceraldehydephosphate dehydrogenase GAPDH is a glycolytic enzyme whose role in cell metabolism and homeostasis is well defined, glyceraldehyde 3-phosphate, while its function in pathologic processes needs further elucidation. These interprotein interactions and post-translational modifications of GAPDH mediate glyceraldehyde 3-phosphate cytotoxic or cytoprotective functions in the manner of a Janus-like molecule.

In addition to this long established metabolic function, GAPDH has recently been implicated in several non-metabolic processes, including transcription activation, initiation of apoptosis , [4] ER-to-Golgi vesicle shuttling , and fast axonal, or axoplasmic transport. This form is composed of four identical kDa subunits containing a single catalytic thiol group each and critical to the enzyme's catalytic function. GAPDH is encoded by a single gene that produces a single mRNA transcript with 8 splice variants, though an isoform does exist as a separate gene that is expressed only in spermatozoa. Enzyme 1. GAPDH uses covalent catalysis and general base catalysis to decrease the very large activation energy of the second step phosphorylation of this reaction. First, a cysteine residue in the active site of GAPDH attacks the carbonyl group of G3P, creating a hemithioacetal intermediate covalent catalysis. The hemithioacetal is deprotonated by a histidine residue in the enzyme's active site general base catalysis.

DOI: The crystal structure of full-length glyceraldehydephosphate dehydrogenase type 1 GAPDH1 from Escherichia coli was determined at 1. Glyceraldehydephosphate dehydrogenase GAPDH is a key enzyme in the glycolytic pathway that catalyzes the conversion of d -glyceraldehyde 3-phosphate to 1,3-diphosphoglycerate. The protein has a certain amount of thermostability. The confirmed recombinant vectors were transformed into E. The collected protein was concentrated and buffer-exchanged.

Various stress conditions induce the nuclear translocation of cytosolic glyceraldehydephosphate dehydrogenase GAPC , but its nuclear function in plant stress responses remains elusive. Here we show that GAPC interacts with a transcription factor to promote the expression of heat-inducible genes and heat tolerance in Arabidopsis. GAPC accumulates in the nucleus under heat stress. The results reveal a cellular and molecular mechanism for the nuclear moonlighting of a glycolytic enzyme in plant response to environmental changes. Glyceraldehydephosphate dehydrogenase GAPDH is a glycolytic enzyme converting glyceraldehydephopshate to 1,3-bisphosphoglycerate.
