The lag in enzymatic activity in vitro often took several hours, while the same process seemed to take only a few minutes in vivo. This discrepancy eventually led to the discovery of an enzyme system in the endoplasmic reticulum of cells that catalyzes the disulfide interchange reaction, and subsequently, the rapid formation of the correct, native disulfide pairing in relatively short order.
