Cystathionine gamma-synthase catalyzes a pyridoxal phosphate dependent synthesis of cystathionine from O-succinyl-L-homoserine (OSHS) and L-cysteine via a gamma-replacement reaction. In the absence of L-cysteine, OSHS undergoes an enzyme-catalyzed, g

S-Adenosylmethionine (SAM) is a central metabolite of Escherichia coli and other cells. Synthesized from methionine and ATP by the enzyme SAM synthetase (5), it is the major methyl donor in metabolism. It is also a precursor of spermidine, formed fro

To characterize the methionine biosynthetic enzyme cystathionine gamma-synthase from Escherichia coli, we have constructed high copy number plasmids containing the metB structural gene but lacking the closely linked metJ regulatory gene. When cloned

In vitro recombination techniques were used to clone the E. coli metJBLF gene cluster in a plasmid vector. Several chimeric plasmids were obtained, analyzed by restriction mapping and characterized genetically. The combined results establish that the

The regulation of the expression of the Escherichia coli metF gene, which codes for 5,10-methylenetet-rahydrofolate reductase (EC 1.1.99.15), has been investigated by using a simplified DNA-directed in vitro system that measures the formation of the

The regulation of the expression of three Escherichia coli met genes, metB, which codes for cystathionine gamma-synthetase (EC 4.2.99.9), metL, which codes for aspartokinase II-homoserine dehydrogenase II (EC 2.7.2.4-EC 1.1.1.3) and metJ, which codes

The genes involved in methionine biosynthesis are scattered throughout the Escherichia coli chromosome and are controlled in a similar but not coordinated manner. The product of the metJ gene and S-adenosylmethionine are involved in the repression of

The effects of supplementation of growth medium with high concentrations of methionine (5 m m ) and/or vitamin B12 (10 n m ) on the activities of five enzymes of the methionine regulon were measured in wild-type Escherichia coli K12, a metJ prototrop

Two of the enzymes involved in the terminal steps of methionine biosynthesis, N 5,10 -methylene-H 4 -folate reductase and the non-B 12 transmethylase, are repressed in a noncoordinate manner by both vitamin B 12 and methionine. The repressions due to

MetJ - mutants of Escherichia coli have elevated nonrepressible levels of the enzymes of methionine biosynthesis and S -adenosylmethionine synthetase (ATP:L-methionine S -adenosyltransferase, EC 2.5.1.6). In E. coli , as in Salmonella typhimurium , t
