Mutations modifying pause C affect alx expression

Translation fusion^a	β-galactosidase units		Position^b
Translation fusion^a	pH 6.8	pH 8.4	Position^b
Wild-type	68 ± 17	531 ± 182	138
A₁₃₂G	182 ± 27	1243 ± 163	138
C₁₃₅U	424 ± 5	1708 ± 225	141
A₁₃₇G	178 ± 30	885 ± 111	140

^aTranslation fusion plasmids carry the alx promoter followed by PRE and the first 53 nucleotides of alx (P_alx-PRE-alx'-'lacZ). Results (in Miller units) are displayed as mean ± standard deviation.

^bThe numbers indicate the estimated location of pause C.
