The transition from the closed to the open complex involves structural changes in the enzyme and the opening of the DNA double helix to reveal the template and nontemplate strands. This “melting” occurs between positions –11 and +2, with respect to the transcription start site.

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)
