We have isolated part of the glnA region of Escherichia coli K-12 as a 6.4 Md DNA fragment on the ColE1 hybrid plasmid pACR1. DNA fragments from pACR1 obtained by cleavage with certain restriction endonucleases were subcloned into the pBR322 cloning vehicle. Recognition sites for the endonucleases BamHI, SmaI, BglII, and EcoRI were localized inside the glnA(More)
The nucleotide (nt) sequence of a 682-bp fragment containing the 3' end of the glnA gene, the region between the glnA and glnL genes, and the 5' end of the glnL gene from Escherichia coli was determined. This segment contains the region coding for the last 107 amino acids (aa) of glutamine synthetase, including the adenylylation site of this enzyme. The(More)
We present measurements of the Fermi surface and underlying band structure of a single layer of indium on Si(111) with square root 7 x square root 3 periodicity. Electrons from both indium valence electrons and silicon dangling bonds contribute to a nearly free, two-dimensional metal on a pseudo-4-fold lattice, which is almost completely decoupled at the(More)
During the larval stages, the visual system of the mosquito Aedes aegypti contains five stemmata, often referred to as larval ocelli, positioned laterally on each side of the larval head. Here we show that stemmata contain two photoreceptor types, distinguished by the expression of different rhodopsins. The rhodopsin Aaop3 (GPROP3) is expressed in the(More)
