The sequence of σ54 is distinctly different from that of all the σ70-like factors, some characteristics about σ54 is given below;
a) The σ54-RNA polymerase binds to the glnA promoter and immediately melt the DNA strands and initiate transcription
b) σ54-polymerase does not require ATP hydrolysis to separate the strands at a start site only require activator such as NtrC
c) σ54-RNA polymerase initiate transcription of glnA promoter only when it is activated by NtrC
d) ATP hydrolysis is required for activation of bound σ54-RNA polymerase by phosphorylated NtrC
