PDI

Protein Disulfide Isomerases

PDI (Protein disulfide isomerases) is a 55-kDa protein and consists of four domains namely a, b, b', a'. PDI is an abundant enzyme in the endoplasmic reticulum (ER). PDI, a prototypic thiol isomerase, is an important oxidase, reductase, isomerase and molecular chaperone. It can distinguish between partially folded, unfolded, and properly folded protein substrates, and catalyze the formation and cleavage of thiol-disulfide bonds during protein folding in the ER. PDI can also maintain active conformation of the β subunit of collagen prolyl 4-hydroxylase and stabilization of the major histocompatibility complex's (MHC) class 1 peptide loading complex (PLC). PDI expression is up-regulated in select types of cancers[1][2].

    Phenylpyruvic acid sodium
    		98.24%
    Phenylpyruvic acid sodium is a endogenous metabolite that participates in the synthesis of 3-phenyllactic acid (PLA) by lactate dehydrogenase. Phenylpyruvic acid is a precursor of the antifungal compound phenyllactic acid. Phenylpyruvic acid can improve the antifungal activity of eight lactic acid bacterial strains through the addition into a dedined growth medium. Phenylpyruvic acid demonstrates improved inhibitory activity against fungal bread contaminants Aspergillus niger and Penicillium roqueforti. Phenylpyruvic acid affects enzyme activity of the pentose phosphate pathway involved in the oxidative phase in rat brain homogenates. Phenylpyruvic acid can reduce glucose-6-phosphate dehydrogenase activity.

    (±)-trans-1,2-Bis(2-mercaptoacetamido)cyclohexane
    (±)-trans-1,2-Bis(2-mercaptoacetamido)cyclohexane is a small-molecule dithiol catalyst with a low thiol pKa value (8.3) and high reduction potential (-0.24 V), capable of mimicking PDI activity. It catalyzes the activation of scrambled ribonuclease A (scrambled ribonuclease A) and promotes the formation of native disulfide bonds, thereby significantly enhancing protein folding efficiency. Adding (±)-trans-1,2-Bis(2-mercaptoacetamido)cyclohexane to the culture medium of Saccharomyces cerevisiae can increase the secretion of exogenously expressed Schizosaccharomyces pombe acid phosphatase by more than threefold. (±)-trans-1,2-Bis(2-mercaptoacetamido)cyclohexane holds great potential for applications in protein production and secretion research.
