Polyphosphate-glucose phosphotransferase. Purification of Mycobacterium tuberculosis H37Ra enzyme to apparent
Acta Biochimica Polonica
|January 1, 1977
Abstract:
1. The enzyme (EC 2.7.1.63) was isolated from glucose-grown M. tuberculosis H37Ra; during the purification procedure, 2-mercaptoethanol, glucose, EDTA and NaCl served as protecting agents. 2. The enzyme was purified about 600-fold. The preparation was homogeneous on polyacrylamide-gel electrophoresis and gave one precipitin line in double immunodiffusion test. Molecular weight of the enzyme determined by Sephadex G-100 filtration was about 118 000. 3. The enzyme preparation showed also glucokinase activity with ATP.
