Probable integrase/recombinase XerC; Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. The XerC- XerD complex is essential to convert dimers of the bacterial chromosome into monomers to permit their segregation at cell division. It also contributes to the segregational stability of plasmids (By similarity).

Phenyloxazoline synthase MbtB (phenyloxazoline synthetase); Involved in the initial steps of the mycobactin biosynthetic pathway. Putatively couples activated salicylic acid with serine or threonine and cyclizes this precursor to the hydroxyphenyloxazoline ring system present in this class of siderophores. Essential for growth in macrophages; Belongs to the ATP-dependent AMP-binding enzyme family. MbtB subfamily.

Bifunctional enzyme MbtA: salicyl-AMP ligase (SAL-AMP ligase) + salicyl-S-ArCP synthetase; Involved in the initial steps of the mycobactin biosynthetic pathway. Catalyzes the salicylation of the aryl carrier protein (ArCP) domain of MbtB through a two-step reaction. The first step is the ATP- dependent adenylation of salicylate to generate a salicyl-AMP intermediate. The second step is the transfer of this activated salicylate to MbtB to form a salicyl-ArCP domain thioester.
