polymerase beta

pol·ym·er·ase be·ta

a class of mammalian DNA polymerases in the nucleus that do not have a role in replication but may function in DNA repair.

More than 90% of the mutations have been found in 81 bp (507 to 533 codons) core region of RNA polymerase beta subunit of rpoB gene6,7.
The Xpert MTB/RIF purifies and concentrates mycobacterium tuberculosis bacilli from sputum samples, isolates genomic material from the captured bacteria by sonication and subsequently amplifies the genomic DNA by PCR.6 The process identifies all the clinically relevant rifampicin resistance inducing mutations in the RNA polymerase beta (rpoB) gene in the mycobacterium tuberculosis genome in a real time format using fluorescent probes called molecular beacons.
