R5P consists of a five-carbon sugar, ribose, and a phosphate group at the five-position carbon. It can exist in open chain form or in furanose form. The furanose form is most commonly referred to as ribose 5-phosphoric acid.

It is a conjugate acid of an aldehydo-D-ribose 5-phosphate (2-). D-Ribose-5-phosphate is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Ribose-5-phosphate has been reported in Drosophila melanogaster and …

Ribose-5-phosphate (R5P) is a necessary precursor for the biosynthesis of nucleosides, which in turn are converted to nucleotides by the addition of phosphate groups.

Riboflavin 5′-phosphate is a supplemental form of vitamin B2. This vitamin is essential for many functions in the body, such as burning fat and supporting NAD+ production. Riboflavin supplements are most helpful if you are deficient in the nutrient.

Ribose-5-phosphate isomerase (Rpi) encoded by the RPIA gene is an enzyme (EC 5.3.1.6) that catalyzes the conversion between ribose-5-phosphate (R5P) and ribulose-5-phosphate (Ru5P). It is a member of a larger class of isomerases which catalyze the interconversion of chemical isomers (in this case structural isomers of pentose ).

The pentose phosphate pathway (PPP) branches from glucose 6-phosphate (G6P), produces NADPH and ribose 5-phosphate (R5P), and shunts carbons back to the glycolytic or gluconeogenic pathway. The PPP has been demonstrated to be a major regulator for ...

2024年10月11日 · Ribose-5-phosphate isomerase (RPI) is a key enzyme in the pentose phosphate pathway (PPP), which plays a critical role in cellular metabolism by balancing nucleotide synthesis and redox homeostasis.

2019年6月7日 · Nature Communications - Ribose-5-phosphate (R5P) is required for DNA synthesis, but how this is regulated during cell cycle progression is unclear. Here the authors report that the cell...

2024年4月8日 · Ribose-5-phosphate (R5P) is a precursor for nucleic acid biogenesis. Here, Guo and Ji et al. show that multiple routes can flexibly supply R5P to enable Toxoplasma gondii growth.
