Protein
Antitoxin VapB4
Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Length
85 amino acids
Function
Antitoxin component of a type II toxin-antitoxin (TA) system. Antitoxin that counteracts the effect of its cognate VapC4 toxin. Upon expression in situ, in M.smegmatis or E.coli neutralizes the effect of cognate toxin VapC4.
Similarity
Belongs to the phD/YefM antitoxin family.
