PathwayStep2671 PathwayStep2670 PathwayStep2673 PathwayStep2672 PathwayStep2674 Miscellaneous substrates Approximately a quarter of the 57 human CYPs still remain "orphans" in the sense that their function, expression sites, and regulation are largely not elucidated. While there is enough experimental evidence to know that all these proteins get made and can catalyze CYP-like reactions in vitro, evidence of in vivo function and substrate specificity is insufficient to allow them to be placed in any of the classes in the functional scheme.
