Mutational analysis of upstream sequences required for transcriptional activation of the klebsiella pneumoniae nifh promoter.... Of the sixteen mutations analysed, only those within the nifH upstream activator sequence (UAS), characterised by a TGT-N10-ACA motif, influenced nifH promoter activity....
Nudeotide sequence and genetic analysis of the region essential for functional expression of the gene for ferredoxin i, fdxn, in rhodobacter capsulatus: sharing of one upstream activator sequence in opposite directions by two operons related to nitrogen f... Two potential —24/—12 promoters were found in front of ORFU1 and 0RFU2, respective-ly, and there was a putative upstream activator sequence (UAS) or NifA-binding site between them....
Structure of the dictyostelium discoideum prestalk d11 gene and protein.... The 273 base pairs upstream from the translation initiator codon are 88% A + T, typical of Dictyostelium upstream sequences, and contain no recognizable upstream activator sequence....
Organization of the gal1-gal10 intergenic control region chromatin.A defined, "far upstream" promoter element, the Upstream Activator Sequence (UAS), which mediates the galactose dependent induction of expression of the GAL10 gene in yeast, is the locus of an anomalous, mainly expression independent...
