Identification
Name: beta-D-ribofuranose
Description:Beta-D-ribofuranose is the cyclic form of D-ribose. Ribose, primarily occurring as D-ribose, is an organic compound that occurs widely in nature. It is an aldopentose, a monosaccharide containing five carbon atoms that in its acyclic form has an aldehyde functional group at one end. Typically, ribose exists in the cyclic form. It comprises the backbone of RNA, a biopolymer that is the basis of genetic transcription. It is related to deoxyribose, as found in DNA, by the removal of one hydroxy group. Once phosphorylated, ribose can become a subunit of ATP, NADH, and several other compounds that are critical to metabolism.

Enzymes

General function:
Involved in riboflavin synthase activity
Specific function:
Riboflavin synthase is a bifunctional enzyme complex catalyzing the formation of riboflavin from 5-amino-6-(1'-D)- ribityl-amino-2,4(1H,3H)-pyrimidinedione and L-3,4-dihydrohy-2- butanone-4-phosphate via 6,7-dimethyl-8-lumazine. The alpha subunit catalyzes the dismutation of 6,7-dimethyl-8-lumazine to riboflavin and 5-amino-6-(1'-D)-ribityl-amino-2,4(1H,3H)- pyrimidinedione
Gene Name:
