Maturase K (matK) is a plant plastidial gene. The protein it encodes is an organelle intron maturase, a protein that splices Group II introns. It is essential for ''in vivo'' splicing of Group II introns. Amongst other maturases, this protein retains only a well conserved domain X and remnants of a

A reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. Reverse transcriptases are used by viruses such as HIV and hepatitis B to replicate their genomes, ...

Universal matK primers can be used for DNA barcoding of angiosperms.
