Significance In this work, we identified the regulatory mechanism of key control point cyanobacterial carbon metabolism, glycolytic phosphoglycerate mutase (PGAM) reaction, converting 3-PGA into 2-PGA and thereby exporting organic from photosynthetic Calvin cycle. We show that PGAM activity is controlled by a small modulator protein PirC (product sll0944 ), which inhibits enzyme through protein...

phosphoenolpyruvate carboxykinase (pepck) has been shown to be present in plants and animals, playing different metabolic roles in different tissues. the basic role of this enzyme is its contribution in the gluconeogenesis pathway. evidences have shown that pepck may play a role in metabolism of nitrogenous compounds in developing seeds of legumes. in this research, pepck gene expression and th...

background: stearoyl-coa desaturase (scd) is a key enzyme that converts saturated fatty acids (sfas) to monounsaturated fatty acids (mufas) in fat biosynthesis. despite being crucial for interpreting scds’ roles across species, the evolutionary relationship of scd proteins across species has yet to be elucidated. this study aims to present this evolutionary relationship based on amino acid sequ...

This article presents the research findings regarding protein, lipid, and carbohydrate-energy metabolism indices in rats under acute (AS) chronic hypokinetic stress (HS) their combinations. HS its combinations with AS were found to decrease protein various extents, causing a negative nitrogen balance body. increased lipid indices, which are factors of atherogenesis body (levels total cholestero...
