Purification, crystallization and preliminary X-ray analysis of NtdA, a putative pyridoxal phosphate-dependent aminotransferase from Bacillus subtilis.
van Straaten K.E., Langill D.M., Palmer D.R., Sanders D.A.
NtdA is a putative sugar aminotransferase that is required for the synthesis of 3,3'-neotrehalosadiamine. The enzyme was purified to homogeneity by means of Ni(2+)-affinity chromatography and was crystallized using the microbatch method. X-ray diffraction data were collected from a single crystal ... >> More
NtdA is a putative sugar aminotransferase that is required for the synthesis of 3,3'-neotrehalosadiamine. The enzyme was purified to homogeneity by means of Ni(2+)-affinity chromatography and was crystallized using the microbatch method. X-ray diffraction data were collected from a single crystal to 2.3 A resolution at the Canadian Light Source (CLS). The crystals belonged to space group P2(1), with unit-cell parameters a = 50.3, b = 106.7, c = 96.7 A, beta = 96.2 degrees, and contained two molecules per asymmetric unit. << Less

The ntd operon in Bacillus subtilis is essential for biosynthesis of 3,3'-neotrehalosadiamine (NTD), an unusual nonreducing disaccharide reported to have antibiotic properties. It has been proposed that the three enzymes encoded within this operon, NtdA, NtdB, and NtdC, constitute a complete set of enzymes required for NTD synthesis, although their functions have never been demonstrated in vitro. We now report that these enzymes catalyze the biosynthesis of kanosamine from glucose-6-phosphate: NtdC is a glucose-6-phosphate 3-dehydrogenase, NtdA is a pyridoxal phosphate-dependent 3-oxo-glucose-6-phosphate:glutamate aminotransferase, and NtdB is a kanosamine-6-phosphate phosphatase. None of these enzymatic reactions have been reported before. This pathway represents an alternate route to the previously reported pathway from Amycolatopsis mediterranei which derives kanosamine from UDP-glucose. << Less
