Fig. 3From: Prediction and characterization of promoters and ribosomal binding sites of Zymomonas mobilis in system biology eraIdentification of promoter candidates with different strengths of strong (a), medium (b), or weak (c) using the omics data of array, RNA-Seq, and proteomics. The sorted normalized values were used to defined the strength of promoters arbitrarily based on their quantile values: in each omics dataset, those sorted in the top 90% were defined as strong promoters, those sorted in the last 10% were defined as weak promoters, and those sorted within 40–60% were defined as medium ones. For a broad representation of weak promoters, six other weak promoters closing to the selection threshold were also included for characterizationBack to article page
