Application

Application Comment Organism
medicine arylsulphatase AtsG , bifunctional glucosamine-1-phosphate acetyltransferase and N-acetylglucosamine-1-phosphate uridyl transferase GlmU and S-adenosyl-L-homocysteine hydrolase SahH are the Mycobacterium tuberculosis proteins that bind to human IL-8. The interactions with IL-8 are characterized by high binding affinity with KD values of 6.83x10-6 M, 5.24x10-6 M and 7.14x10-10 M, respectively. Strains overproducing the enzymes show a significantly increased number of intracellularly located bacilli compared with those of wild-type Mycobacterium tuberculosis

General Information

General Information Comment Organism
physiological function the enzyme is one of the pathogen proteins that bind to human interleukin-8, IL-8. The binding interaction of mycobacterial proteins AtsG, GlmU and SahH with human IL-8 may indicate that these proteins participate in the modulation of the early events of infection with tubercle bacilli and could affect pathogen attachment to target cells. Interleukin-8 belongs to the family of CXC chemokines and functions as a chemoattractant and activator of different subsets of leukocytes Mycobacterium tuberculosis
