RESUMO
The glk gene from Bacillus megaterium, which encodes glucose kinase, was isolated and analyzed. Disruption by a transcriptional glk-luxAB fusion indicated that glk is the only glucose kinase gene in that strain but did not affect growth of that mutant on glucose. Determination of luciferase activity under various growth conditions revealed constitutive transcription of glk. Expression of a xylA-lacZ fusion was repressed by glucose in the strain with the glk disruption about twofold less efficiently than in the wild type. The potential contribution of glk expression to glucose repression is discussed.
