Antigen 85 Complex B (Ag85B)

Target
Ag85B
Molecular classification
Enzyme, Mycolyltransferase, Fibronectin-binding protein
01

Overview

Antigen 85B (Ag85B) is an abundant secreted enzyme crucial for Mycobacterium tuberculosis cell wall construction via mycolic acid transfer reactions; it binds host fibronectin aiding infection establishment; it provokes robust immune responses making it valuable both diagnostically and as a vaccine/drug target against TB.
