- In biochemistry,
chelatases are
enzymes that
catalyze the
insertion ("metalation") of
naturally occurring tetrapyrroles. Many tetrapyrrole-based cofactors...

corresponding cobalt chelatases are not homologous. However,
aerobic cobalt chelatase subunits CobN and CobS are
homologous to Mg-
chelatase subunits BchH and...

- the
metal cation is
inserted into
protoporphyrin IX by
enzymes called chelatases. For example,
ferrochelatase converts the

ferrochelatase is a
class II
chelatase, i.e. it does not
require ATP for its
activity unlike class I
