Family
Phosphopentose epimerase belongs to two protein families of increasing hierarchy. This enzyme belongs to the isomerase family which acts on carbohydrates and their derivatives. In addition, the Structural Classification of Proteins database has defined the “ribulose phosphate binding” superfamily for which this epimerase is a member. Other proteins included in this superfamily are 5‘-monophosphate decarboxylase (OMPDC), and 3-keto-l-gulonate 6-phosphate decarboxylase (KGPDC).

Famous quotes containing the word family:
“Some [adolescent] girls are depressed because they have lost their warm, open relationship with their parents. They have loved and been loved by people whom they now must betray to fit into peer culture. Furthermore, they are discouraged by peers from expressing sadness at the loss of family relationships—even to say they are sad is to admit weakness and dependency.”
—Mary Pipher (20th century)
“If you understand why a monkey in a family is always mocked and harassed, you understand why monks are rejected by all—both old and young.”
—François Rabelais (1494–1553)
“It is as when a migrating army of mice girdles a forest of pines. The chopper fells trees from the same motive that the mouse gnaws them,—to get his living. You tell me that he has a more interesting family than the mouse. That is as it happens.”
—Henry David Thoreau (1817–1862)
