The cAMP receptor protein (Crp) is a global transcriptional regulator that binds sequence-specific promoter elements when associated with cAMP. In the motile cyanobacterium Synechocystis sp. strain PCC 6803, intracellular cAMP increases when dark-adapted cells are illuminated. Previous work has established that Crp binds proposed Crp target sites upstream of slr1351 (murF), sll1874 (chlA(II)), ...

Formate oxidation coupled to nitrate reduction constitutes a major anaerobic respiratory pathway in Escherichia coli. This respiratory chain consists of formate dehydrogenase-N, quinone, and nitrate reductase. We have isolated a recombinant DNA clone that likely contains the structural genes, fdnGHI, for the three subunits of formate dehydrogenase-N. The fdnGHI clone produced proteins of 110, 3...

NARL has active array radar which has been designed, developed and tested at 1280 MHz. This system comprises of planar microstrip patch antenna array fed by solid-state transreceiver (TR) modules, two-dimensional (2D) passive beam forming network (BFN) and direct IF digital receiver (DRx). Errors are the common factors that affect the data. The common errors are Random errors and Systemic error...

The respiratory control of adhE, which encodes ethanol (alcohol) dehydrogenase in Escherichia coli, was examined at the transcriptional level by using various phi (adhE'-lacZ) adhE+ merodiploid strains. Expression of the adhE'-lacZ operon fusion was increased about eightfold by anaerobic growth. Under anaerobic growth conditions, provision of nitrate lowered the level of expression. Nitrate rep...
