The nucleotide sequence is described of a region of the Escherichia coli chromosome
extending from oriC to phoS that also includes the loci gid, unc and glmS. Taken with known …

Some properties of glutamine synthetase I (GSI) and GSII are described for a fast-growing
Rhizobium sp.(Rhizobium trifolii T1), a slow-growing Rhizobium sp.(Rhizobium japonicum …

In Escherichia coli K 12 either of the two genes argF and argI is able to produce a functional
ornithine carbamoyltransferase. When both are active in the same cell the two gene …

Asparaginyl-tRNA (Asn-tRNA) and glutaminyl-tRNA (Gln-tRNA) are essential components of
protein synthesis. They can be formed by direct acylation by asparaginyl-tRNA synthetase …

At least four electrophoretically distinct forms of aspartate aminotransferase were detected in
root nodules of soybeans (Glycine max L.). Two forms originated from the cytosol of the host …

The complete nucleotide sequence of argF is presented, together with that of an operator-
constitutive mutant. ArgF is compared with the other gene coding for ornithine …

Background: Amidotransferases use the amide nitrogen of glutamine in a number of
important biosynthetic reactions. They are composed of a glutaminase domain, which …

This review makes a comprehensive survey of microbial amylases, ie alpha-amylase, beta-
amylase and glucoamylase. Amylases are among the most important enzymes and are of …

Glutamate semialdehyde aminotransferase was purified to homogeneity from pea leaves.
The enzyme has an absorption spectrum with maxima at 345 and 416 nm. These …

Glutamate dehydrogenase (GDH) is generally regarded as the major route of ammonia
incorporation in higher plants [1, 2] as well as in microorganisms [3]. Recent studies with …
