Metabolic scheme illustrating the mechanisms of response of Laribacter hongkongensis to different environment and stress as deduced from its genome sequence. Different environmental stresses and the corresponding genes in L. hongkongensis are shown as indicated (separated by broken lines). Line arrows indicate the flow of pathway. Solid arrows indicate the flow of substances through transporter. Transporters including uniporter, antiporter, symporter, and P-type ATPase are shown as blue rectangular box. ABC transporters are shown as composite figure of 2 circles, 2 ovals and 1 horizontal oval. Integrated view of central metabolism is presented as yellow circle. Integrated view of gene regulation is presented as light blue rectangle. arc, arginine deiminase; Cd2+, Cadmium(II) ion; Co2+, Cobalt(II) ion; Cu2+, Copper(II) ion; Fe3+, ferrous ion; H+, hydrogen ion; H2CO3, hydrogen carbonate; Mg2+, Magnesium(II) ion; Na+, Sodium ion; NH3, ammonia; Ni2+, Nickel(II) ion; K+, Potassium ion; ROS, reactive oxygen species; UreI, urea transporter; UV, ultraviolent light.
