Figure 2.

Genes selected from data presented in Fig. 1 and grouped into categories on the basis of their probable biological role. (a) ATP metabolism; (b) locomotion and contraction; (c) protein translation; (d) iron metabolism; (e) antigrowth and proliferation; (f) amino acid metabolism; and (g) cryptic role. Note that only a small fraction of the unknown genes discovered in this work are shown. (h) Northern blot analysis confirming the expression of a number of hypoxia-regulated genes in liver of G. mirabilis. The expression of β-actin, shown for reference, does not appear to significantly change in liver.
