After removing ribosomal proteins, 20 proteins with a promising rank in the RAPDOR analysis are given together with their SVM prediction of RNA binding (Supplementary Data 2). The gene name or locus tag is given, followed by the ANOSIM value (ANO), the mean JSD, the relative shift in the number of fractions, the absolute rank assigned by RAPDOR and SVM, comments and annotation. n/a indicates an SVM score below the threshold.
Asterisks indicate that the homologs in Nostoc 7120 also showed RNA-dependent shifts46. See also Figs. 5 and 6 and Supplementary Data 2. Boldface letters indicate RBPs validated in PNK assays (Fig. 7).
