| nucleoplasm | cellular component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
| peroxisome | cellular component | A small organelle enclosed by a single membrane, and found in most eukaryotic cells. Contains peroxidases and other enzymes involved in a variety of metabolic processes including free radical detoxification, lipid catabolism and biosynthesis, and hydrogen peroxide metabolism. [GOC:pm, PMID:9302272, UniProtKB-KW:KW-0576] |

Involved In
This protein is involved in 5 target(s):
| Target | Category | Definition |
|---|---|---|
| pentose-phosphate shunt | biological process | The metabolic process in which glucose-6-phosphate is oxidized to form carbon dioxide (CO2) and ribulose 5-phosphate, coupled to reduction of NADP+ to NADPH; ribulose 5-P then enters a series of reactions that can yield biosynthetic precursors (ribose-5-phosphate and erythrose-4-phosphate) and glycolytic intermediates (fructose-6-phosphate and glyceraldehyde-3-phosphate). [GOC:pde, ISBN:0198506732, MetaCyc:PENTOSE-P-PWY] |
| pentose-phosphate shunt, non-oxidative branch | biological process | The branch of the pentose-phosphate shunt which does not involve oxidation reactions. It comprises a series of sugar phosphate interconversions, starting with ribulose 5-P and producing fructose 6-P and glyceraldehyde 3-P. [ISBN:0198506732, MetaCyc:NONOXIPENT-PWY] |
| regulation of growth | biological process | Any process that modulates the frequency, rate or extent of the growth of all or part of an organism so that it occurs at its proper speed, either globally or in a specific part of the organism's development. [GOC:ems, GOC:mah] |
| glyceraldehyde-3-phosphate biosynthetic process | biological process | The chemical reactions and pathways resulting in the formation of glyceraldehyde-3-phosphate, an important intermediate in glycolysis. [GOC:ai] |
| xylulose 5-phosphate biosynthetic process | biological process | The chemical reactions and pathways resulting in the formation of xylulose 5-phosphate. [GOC:bf, GOC:TermGenie] |
