Bold fonts were used to highlight genes considered biologically relevant for the present study (surface-or motility-related genes). Full array datasets are in public databases as described in Methods. Interestingly, four genes encoding proteins of the Hop outer membrane family were identified as differentially expressed in the HP0256 mutant by microarray analysis (hopA/BIBW2992 datasheet HP0229, hopV/HP1469, babA/HP1423 and babB/HP0896). hopA was four fold down-regulated, whereas the other three Hop genes were up-regulated. HP1339 and HP1340, encoding respectively the biopolymer transport proteins ExbB and ExbD, were up-regulated in the HP0256 mutant. ExbB and ExbD in E. coli interact with the TonB-dependent energy transduction complex [35]. In E. coli, TonB is involved in the transduction of energy between the cytoplasmic membrane and the outer membrane [36]. Five genes involved in lipopolysaccharide (LPS) production were differentially expressed: HP0093 (alpha-(1,2)-fucosyltransferase), HP0094 (alpha-(1,2)-fucosyltransferase), HP0805 (lipooligosaccharide biosynthesis-associated protein) and HP0310 (contains a polysaccharide deacetylase Pfam domain).
