iP and tZ are active, and their derivatives are abundant, but they are susceptible to degradation by CK oxidase (CKX).

all cZ‐type CKs are derived from tRNA degradation in cZ‐abundant plant species, such as O. sativa.

cZ is thought to be less active and relatively more stable than tZ and iP because of its low affinity for CKX. cZ and its conjugates are more abundant than tZ‐ and iP‐type CKs in Z. mays, O. sativa, chickpea (Cicer arietinum) and a moss (Physcomitrella patens)
