ABSTRACT
Polyacrylamide gel electrophoresis (PAGE) technique was standardised to demonstrate some key enzymes of glycolysis, hexose mono phosphate (HMP) pathway and tricarboxylic acid cycle in slow growing mycobacteria (M. avium. M. gastri) as well as in fast growing mycobacteria (M. vaccae, M. phlei). The enzymes studied were lactate dehydrogenase (LDH) glucose-6-phosphate dehydrogenase (G6PD), aconitase, isocitrate dehydrogenase (ICD), succinic dehydrogenase (SDH), fumerase and malate dehydrogenase (MDH). All the three pathways were found to be operative in slow as well as fast growing mycobacteria. Using this technique M. leprae specific MDH activity was demonstrated in the cell free extract of M. leprae. It's (MDH) electrophoretic mobility on gels lies in the range shown by other mycobacterial species studied and was distinct from that of host MDH. It appears that PAGE offers a useful tool for metabolic characterization of M. leprae using infected tissues.
