- Cloning and expression of the Lactococcus lactis purDEK genes, required for growth in milkD Nilsson
Department of Physiology and Metabolism, Chr Hansen A S, DK 2970 Horsholm, Denmark
Appl Environ Microbiol 64:4321-7. 1998..No secondary transcription start points were mapped in or close to this region, indicating that a putative activator site and not a promoter was deleted or partly destroyed...
- Glucose/citrate cometabolism in Lactococcus lactis subsp. lactis biovar diacetylactis with impaired alpha-acetolactate decarboxylaseM Curic
Chr Hansen A S, Research and Development, Hørsholm, Denmark
Metab Eng 1:291-8. 1999..The strain with impaired alpha-acetolactate decarboxylase activity accumulated alpha-acetolactate which resulted in an increased diacetyl formation compared to the wild-type strain, under aerobic and anaerobic conditions...
- Isolation of purine auxotrophic mutants of Lactococcus lactis and characterization of the gene hpt encoding hypoxanthine guanine phosphoribosyltransferaseD Nilsson
Department of Genetics, Chr Hansen s Laboratorium Denmark A S, Hørsholm, Denmark
Mol Gen Genet 235:359-64. 1992..lactis resulted in an increase in HGPRT activity. In vitro transcription and translation analysis showed that the fragment coded for a polypeptide with M(r) of 22,000. The nucleotide sequence of this hpt gene was determined...
- Activation control of pur gene expression in Lactococcus lactis: proposal for a consensus activator binding sequence based on deletion analysis and site-directed mutagenesis of purC and purD promoter regionsM Kilstrup
Department of Microbiology, Technical University of Denmark, DK2800 Lyngby, Denmark
J Bacteriol 180:3900-6. 1998..All results support the idea that purC and purD transcription is regulated by a transcriptional activator binding to the PurBox sequence...
- Primary structure of the tms and prs genes of Bacillus subtilisD Nilsson
Enzyme Division, University Institute of Biological Chemistry B, Copenhagen, Denmark
Mol Gen Genet 218:565-71. 1989..The deduced Tms amino acid sequence was found to be 43% similar to the deduced amino acid sequence of ecourfl, a gene of E. coli with unknown function...
