Clustered genes for galactose metabolism from Streptococcus mutans cloned in Escherichia coli. 1983

M Smorawinska, and J C Hsu, and J B Hansen, and E K Jagusztyn-Krynicka, and Y Abiko, and R Curtiss

DNA cloned into Escherichia coli from a serotype c strain of Streptococcus mutans allowed a galKTE mutant to utilize galactose for growth. However, the DNA does not appear to encode enzymes of the Leloir pathway used by E. coli, but rather appears to encode enzymes of the tagatose phosphate pathway.

UI MeSH Term Description Entries
D003001 Cloning, Molecular The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells. Molecular Cloning
D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
D005690 Galactose An aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. Deficiency of galactosyl-1-phosphate uridyltransferase (GALACTOSE-1-PHOSPHATE URIDYL-TRANSFERASE DEFICIENCY DISEASE) causes an error in galactose metabolism called GALACTOSEMIA, resulting in elevations of galactose in the blood.

D006600 Hexosephosphates
D013295 Streptococcus mutans A polysaccharide-producing species of STREPTOCOCCUS isolated from human dental plaque.
