Am. Griffin et al., CLONING OF THE ACEF GENE ENCODING THE PHOSPHOMANNOSE ISOMERASE AND GDP-MANNOSE PYROPHOSPHORYLASE ACTIVITIES INVOLVED IN ACETAN BIOSYNTHESISIN ACETOBACTER-XYLINUM, FEMS microbiology letters, 154(2), 1997, pp. 389-396
The aceF gene from Acetobacter xylimum was identified and cloned from
a genomic DNA library. The complete DNA sequence was determined and co
mputer analysis of the translated gene sequence revealed homology with
the deduced amino acid sequence of xanB from Xanthomonas campestris.
Therefore aceF is likely to encode a bifunctional enzyme with mannose-
6-phosphate isomerase (PMI) and GDP-mannose pyrophosphorylase (GMP) ac
tivities. PMI and GMP activities were detected in strains of Escherich
ia coil expressing the cloned aceF gene.
