CRYSTAL STRUCTURE ANALYSIS OF CATALASE FROM EXIGUOBACTERIUM OXIDOTOLERANS
OverviewOverview
A catalase that exhibits a high level of activity and a rapid reaction, with organic peroxides has been purified from Exiguobacterium, oxidotolerans T-2-2T (EKTA catalase). The amino acid sequence of EKTA, catalase revealed that it is a novel clade 1 catalase. Amino acid residues, in the active site around the protoheme are conserved in the primary, structure of EKTA catalase. Although the general interactions of molecules, larger than hydrogen peroxide with catalases are strongly inhibited, because of the selection role of long and narrow channels in the substrate, reaching the active site, the formation rate of reactive intermediates, (compound I) in the reaction of EKTA catalase with peracetic acid is 77, times higher than that of bovine liver catalase (BLC) and 1200 times, higher than ...
