Examination of theStreptococcus gordoniichromosomal region, which lies immediately upstream of the glucosyltransferase positive regulatory determinantrgg, revealed two open reading frames. Based on nucleotide sequences, these genes were similar to theListeria monocytogenes lemAgene, which is involved in antigen presentation, and theEscherichia coli htpXheat shock gene, which has an unknown function. Northern hybridization analysis indicated thatS. gordonii lemAandhtpXgenes were associated with aca.1.7‐kb polycistronic transcript. Although levels of thelemA/htpXtranscript did not increase in response to heat to levels seen withdnaKcontrols, insertional inactivation ofhtpXresulted in changes in adhesiveness, cellular morphology and detergent‐extractable surface antigens in cells grown at 41°C, implying thathtpXmay be involved in surface protein expression. Insertional inactivation oflemAandhtpXindicated that, despite their proximity torggand the structural gene,gtfG, these upstream genes do not affectS. gordoniiglucosyltransferase activity.
