Derivatives of one molecule, rifamycin B, which itself possess minimal antibiotic activity yielded several highly active antibiotics, one of the earliest which was used as a medicine being rifamycin SV, which was introduced in some countries for the parenteral and topical treatment of infections due to gram-positive bacteria and infections of ...
It produces the rifamycin antibiotics (e.g., rifamycin SV), which are used to treat mycobacterial diseases such as tuberculosis and leprosy.

In enzymology, a rifamycin-B oxidase (EC 1.10.3.6) is an enzyme that catalyzes the chemical reaction rifamycin B + O 2 ⇌ {\displaystyle \rightleftharpoons } rifamycin O + H 2 O 2 Thus, the two substrates of this enzyme are rifamycin B and O 2 , whereas its two products are rifamycin O and H 2 O 2 .
