A0A1V4XAQ1 · A0A1V4XAQ1_9BACT

Function

function

Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.
The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.
