PPIB | cytoplasmic cytophilin, interaction with phosphate acetyltransferase leads to enhanced activity and alteration in Km value. PPIase activity is not essential for these interactions, as PPIB F99A active site mutant still interacts with phosphate acetyltransferase, but PPIB activity is responsible for the observed phosphate acetyltransferase activity enhancement | Azotobacter vinelandii |
