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

Cobalt chelatase (EC 6.6.1.2) is an
enzyme that
catalyzes the
chemical reaction ATP +
hydrogenobyrinic acid a,c-diamide + Co2+ + H2O ⇌ {\displaystyle...
- EC 6.6
includes ligases used to form nitrogen-metal bonds, as in the
chelatases Some
ligases ****ociate with
biological membranes as
peripheral membrane...
- the
metal cation is
inserted into
protoporphyrin IX by
enzymes called chelatases. For example,
ferrochelatase converts the
compound into heme B (i.e. Fe-protoporphyrin...
- GUN4
regulates chlorophyll synthesis, by
activating the
enzyme Magnesium chelatase,
which catalyzes the
insertion of Mg2+ into
Protoporphyrin IX. Bilins...

Other names in
common use
include CbiK, CbiX, CbiXS,
anaerobic cobalt chelatase,
cobaltochelatase [ambiguous], and
sirohydrochlorin cobalt-lyase (incorrect)...

divalent metal cations to
tetrapyrrole structures. For example,
magnesium chelatase adds
magnesium to
protoporphyrin IX in the
first step of bacteriochlorophyll...
-
ferrochelatase is a
class II
chelatase, i.e. it does not
require ATP for its
activity unlike class I
chelatases such as Mg-
chelatase. In E. coli, all three...
