Genetic studies have implicated the evolutionary novel, anthropoid primate-specific gene locus G72/G30 in psychiatric diseases. This gene encodes the protein LG72 that has been discussed to function as a putative activator of the peroxisomal enzyme D-amino-acid-oxidase (DAO) and as a mitochondrial protein. We recently generated 'humanized' bacterial(More)
Two genes, hom (encoding homoserine dehydrogenase) and thrB (encoding homoserine kinase), of the threonine biosynthetic pathway are clustered in the chromosome of Brevibacterium lactofermentum in the order 5' hom-thrB 3', separated by only 10 bp. The Brevibacterium thrB gene is expressed in Escherichia coli, in Brevibacterium lactofermentum, and in(More)
A cloned 9.6-kb fragment of Brevibacterium lactofermentum DNA, carrying the entire trp operon and upstream regulatory sequences, produces a polycistronic 7.0-kb transcript as detected by hybridization with an internal probe. The transcription start point (tsp) was identified by S1 mapping. The operator-promoter (OP) region subcloned in Escherichia coli and(More)
The thrC gene of Brevibacterium lactofermentum was cloned by complementation of Escherichia coli thrC auxotrophs. The gene was located by deletion mapping and complementation analysis in a 2.9-kb Sau3AI-HindIII fragment of the genome. This fragment also complemented a B. lactofermentum UL1035 threonine auxotroph that was deficient in threonine synthase. A(More)
