Light gray parameters were selected by the model but the confidence for their estimated coefficients is not sufficiently high to be considered as significant (p-value>0.05).

AMI = Amino acid biosynthesis, CEL = cellular process, COF = biosynthesis of cofactors, ENV = cell envelope, FAT = fatty acids metabolism, INT = central intermediary metabolism, NRJ = energy metabolism, OTH = other categories, PUR = purines, pyrimidines, nucleosides and nucleotides, REG = regulatory functions, REP = replication, TRD = translation, TRS = transcription, TSP = transport and binding proteins.
