obsolete bacterial-type RNA polymerase activity https://github.com/geneontology/go-ontology/issues/16738 true molecular_function This term was obsoleted because the activity is the same as its parent. krc 2010-10-19T03:36:01Z GO:0001061 OBSOLETE. Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template that contains a bacterial-type 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'. DNA-directed RNA polymerase activity
