Nitrogen metabolism in prokaryotes involves the coordinated expression of a large number
of enzymes concerned with both utilization of extracellular nitrogen sources and intracellular …

The linkage map of Escherichia coli K-12 depicts the arrangement of genes on the circular
chromosome of this organism. The basic units of the map are minutes, determined by the …

An updated compilation of 300 E. coli mRNA promoter sequences is presented. For each
sequence the most recent relevant paper was checked, to verify the location of the …

In the previous chapter we have outlined the pathways of nitrogen metabolism in higher
plants, with particular emphasis placed on the mechanisms by which ammonia is …

Studies of enzymes involved in nitrogen assimilation in higher plants have an impact on
both basic and applied plant research. First, basic research in this area should uncover the …

Publisher Summary This chapter discusses the diversity of iron–sulfur proteins. From
consideration of the primary and tertiary structure of the iron–sulfur proteins determined so …

Ammonium ion assimilation constitutes a central metabolic pathway in many organisms, and
glutamate synthase, in concert with glutamine synthetase (GS, EC 6.3. 1.2), plays the …
