Bioinformatic analysis of the nfs locus. Motifs were predicted by SMART [87, 88]. TM, transmembrane region; TPR, tetratrico peptide repeat domain involved in mediation of protein-protein interactions [69]; FHA, Fork head-associated domain involved in binding to phospho-threonine containing proteins [70]. Localization was predicted by CELLO [74]. OM: outer membrane; C, cytoplasmic; P, periplasmic. * based on amended start codon positions (see text).
