activation of gene transcription
activation of gene transcription by high level protein
"A low concentration of GerE activated cotB transcription by final sigma(K) RNA polymerase, whereas a higher concentration was needed to activate transcription of cotX or cotC." (Reference: http://www.ncbi.nlm.nih.gov/pubmed/10075739)
an activation of gene transcription that is achieved by a high level of a protein
