Abstract
This invention relates to sarcosine oxidase having the following physico-chemical properties: (a) action: oxidatively hydrolyzing 1 mole sarcosine to give 1 mole glycine, 1 mole formaldehyde, and 1 mole hydrogen peroxide; (b) substrate specificity: specific for sarcosine; (c) optimum pH: 7.0-8.0; (d) stable pH range: 7.0-9.5; (e) suitable temperature range for action: 50° C.; (f) thermostability: 55° C. or less; and (g) molecular weight: 44,000 daltons (when estimated roughly from the amino acid sequence of the wild-type), and to a process for producing the sarcosine oxidase, comprising the steps of culturing a microorganism having an ability to produce the sarcosine oxidase and collecting the sarcosine oxidase from the culture are provided.
