H. lacusprofundi carbohydrate utilization gene cluster in chromosome II. The predicted genes, shown to scale, with those in rightward transcriptional orientation in red and leftward orientation in blue. Predicted gene functions are (from left to right) Hlac_2855 and 2857, ISH3 and IS4 family transposases; Hlac_2860, 2-keto-3-deoxy-6-phosphogluconate aldolase/4-hydroxy-2-oxoglutarate aldolase; Hlac_2861, IclR family transcriptional regulator; Hlac_2862, sugar-binding periplasmid protein; Hlac_2863, ABC-type sugar transport system permease component; Hlac_2864, sugar permease; Hlac_2865, ABC-type sugar transport system; ATPase component; Hlac_2866, L-alanine-DL-glutamate epimerase and related enzymes of enolase; Hlac_2867, short-chain dehydrogenase/reductase SDR; Hlac_2868, β-galactosidase; Hlac_2869, α-galactosidase; Hlac_2870, sugar kinase, and Hlac_2871 and 2872, IS200 family and IS605 OrB family transposases.
