Mycobacterium tuberculosis Antigen Ag85A (Ag85A)

Target
Ag85A
Molecular classification
Enzyme, Mycolyltransferase, Diacylglycerol acyltransferase, Secretory protein
01

Overview

Ag85A is a major secretory protein and mycolyltransferase enzyme produced by *Mycobacterium tuberculosis*. It is part of the antigen 85 complex and plays critical roles in cell wall biosynthesis, host-pathogen interactions, and bacterial persistence. Ag85A elicits strong T-cell mediated immune responses, making it an attractive candidate for TB vaccine development.
