[9] [10] If rifamycin binds the polymerase after the chain extension process has started, no inhibition is observed on the biosynthesis, consistent with a steric-occlusion mechanism. Single step high level resistance to the rifamycins occurs as the result of a single amino acid change in the bacterial DNA dependent RNA polymerase.
Rifampicin, also known as rifampin, is an ansamycin antibiotic used to treat several types of bacterial infections, including tuberculosis (TB), Mycobacterium avium complex, leprosy, and Legionnaires' disease. [3]
It produces the rifamycin antibiotics (e.g., rifamycin SV), which are used to treat mycobacterial diseases such as tuberculosis and leprosy. [2] The type strain of Amycolatopsis rifamycinica (DSM 46095) has been reclassified several times. When it was first isolated from a French soil sample in 1957, it was identified as Streptomyces ...

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 .
