The promoter constructs used are shown in parentheses. All mutant strains contained pEL4.
Numbers indicate the open reading frame (ORF) designation for C. crescentus NA1000 as deposited in GenBank.
Obtained from the sequence databases.
Values are averages and standard deviations of data obtained in three experiments. Data refer to measurements at 24-h time point.
