Term Name:	mitochondrial single subunit type RNA polymerase activity
Synonyms:
Definition:	Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template that contains a single-subunit-type mitochondrial RNA polymerase-specific promoter to direct initiation and catalyses DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.
