Isolation and properties of cytochrome c peroxidase from Pseudomonas denitrificans. 1979

A F Coulson, and R I Oliver

The isolation of cytochrome c peroxidase, cytochrome c4, cytochrome c-551 and azurin from Pseudomonas dentrificans is described. The peroxidase has a molecular weight of 63,000 and an isoelectric point of 5.6. Its absorption spectrum suggests that it contains two haem c groups/molecule. Preliminary steady-state kinetic data are reported with cytochromes c-551 and c4 and azurin as the second substrate.
