5.1.3.1 | Co2+ | Co2+ is able to activate the enzyme in vitro | Escherichia coli | |
5.1.3.1 | Fe2+ | the enzyme employs a ferrous iron atom as a solvent-exposed cofactor | Escherichia coli | |
5.1.3.1 | Mn2+ | manganese can activate the enzyme in vitro in place of iron converting the enzyme to a form that is unaffected by H2O2 | Escherichia coli | |
5.1.3.1 | additional information | Ca2+, Cd2+, Cu2+, Mg2+, and Ni2+ do not activate the enzyme | Escherichia coli | |
5.1.3.1 | Zn2+ | Zn2+ is able to activate the enzyme in vitro | Escherichia coli |

5.1.3.1 | ribulose-5-phosphate 3-epimerase is vulnerable to H2O2 damage in vivo. H2O2 rapidly oxidizes the Fe2+ in a Fenton reaction, the oxidized iron is released immediately, causing a loss of activity. When purified enzyme is loaded with Mn2+, Co2+, or Zn2+, there is no loss in activity when challenged with H2O2 | Escherichia coli |
