Sequence of the gat operon for galactitol utilization from a wild-type strain EC3132 of Escherichia coli.
Nobelmann B., Lengeler J.W.
The sequence of the gat operon for galactitol (Gat) utilization from a wild-type isolate of Escherichia coli, strain EC3132, is presented. The operon comprises 7 open reading frames (ORFs) called gatYZABCDR. The genes are transcribed from a promoter located upstream of gatY. Genes gatABC encode th ... >> More
The sequence of the gat operon for galactitol (Gat) utilization from a wild-type isolate of Escherichia coli, strain EC3132, is presented. The operon comprises 7 open reading frames (ORFs) called gatYZABCDR. The genes are transcribed from a promoter located upstream of gatY. Genes gatABC encode the substrate-specific domains IIA, IIB and IIC of a galactitol-specific Enzyme II (EIIGat) of the phospho enol pyruvate-dependent carbohydrate:phosphotransferase system (PTS); gatD encodes an NAD-dependent Gat 1-phosphate dehydrogenase; and gatY an enzyme which hydrolyses tagatose 1,6-bisphosphate; gene gatZ is required in a cell to show a Gat+ phenotype, but its physiological function has not yet been identified; gatR encodes a repressor for the gat operon. All genes are highly similar to the gat genes from E. coli K-12; in this organism they map at 46.70 min of the gene map, equivalent to about 2180-2186 kbp. << Less

Molecular cloning, characterization, and nucleotide sequence of the tagatose 6-phosphate pathway gene cluster of the lactose operon of Lactococcus lactis.
van Rooijen R.J., van Schalkwijk S., de Vos W.M.
The tagatose 6-phosphate pathway gene cluster (lacABCD) encoding galactose-6-phosphate isomerase, tagatose-6-phosphate kinase, and tagatose-1,6-diphosphate aldolase of Lactococcus lactis subsp. lactis MG1820 has been characterized by cloning, nucleotide sequence analysis, and enzyme assays.

The tagatose 6-phosphate pathway gene cluster (lacABCD) encoding galactose-6-phosphate isomerase, tagatose-6-phosphate kinase, and tagatose-1,6-diphosphate aldolase of Lactococcus lactis subsp. lactis MG1820 has been characterized by cloning, nucleotide sequence analysis, and enzyme assays. Transcription studies showed that the four tagatose 6-phosphate pathway genes are the first genes of the lactose-inducible lactose-phosphotransferase operon consisting of the lacABCDFEGX genes. Using a T7 expression system, it could be shown that the lacA, lacB, lacC, and lacD genes code for proteins with apparent molecular masses of 15, 19, 33, and 36 kDa, respectively. Cell-free extracts of induced and noninduced Escherichia coli cells expressing the lacABCD genes were used to determine the functions of the encoded proteins. Expression of both lacA and lacB was required to obtain galactose-6-phosphate isomerase activity. The lacC gene codes for tagatose-6-phosphate kinase, the deduced amino sequence of which is similar to that of E. coli Pfk-2 phosphofructokinase, and Staphylococcus aureus LacC protein. The tagatose-1,6-diphosphate aldolase is encoded by the lacD gene, and its deduced primary sequence, which is homologous to that of the S. aureus LacD protein, predicts an amino acid composition which is virtually identical to that of the previously purified L. lactis E8 tagatose-1,6-diphosphate aldolase. << Less
