heme
-
isoenzymes I and II contain protoheme, isoenzyme II contains chlorine-type heme
heme
-
the monofunctional catalase contains a chlorine-type heme, the catalase-peroxidase has protoheme IX
heme
all isoforms have chlorine instead of ferro-protoheme IX at the active site
heme
-
dependent on, contains 1 protoheme IX group per KatA 54 kDa polypeptide
heme
-
in wild-type, primarily high-spin. In mutant Y111A, substantial increase in hexa-coordinate low-spin heme
heme
-
substrate isonicotinic hydrazide binds with high affinity to a small protion of ferric enzyme in a six-coordinate heme iron form, binding is associated with a large enthalpie loss. Binding parameters do not depend on pH in the range of pH 5-8
heme
CAT-1 tetramer includes 3450 water molecules and four heme groups
heme
binding sites of the distal region of heme with Val106, Thr128 and Phe143, and proximal sites of heme with Tyr348 and Arg355 are well conserved
heme
-
EsCAT contains a proximal heme-ligand signature motif, 350RLFSYNDTH358. Each monomer contains a single heme
heme
protoporphyrin IX, protein displays a Soret peak at 405 nm
NADPH
-
Each monomer contains a NADPH bound on the surface of each monomer by 12 amino acid residues and protects the enzyme from oxidation by its substrate, H2O2
additional information
the enzyme contains a NADPH-binding site with His184, Arg193, Val292 and Lys295
-
additional information
-
the heme component is cis-hydroxychlorin gamma-spirolactone
-
additional information
-
protein displays absorption maxima at 280 nm, 405 nm and 588 nm
