Taxonomic identifier

1773 [NCBI]

Taxonomic lineage

Bacteria › Actinobacteria › Actinobacteridae › Actinomycetales › Corynebacterineae › Mycobacteriaceae › Mycobacterium › Mycobacterium tuberculosis complex

Protein attributes

Sequence length	790 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Can catalyze the hydrolysis of ATP in the presence of single-stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with lexA causing its activation and leading to its autocatalytic cleavage. HAMAP MF_00268 PI-MtuI is an endonuclease. HAMAP MF_00268
Subcellular location	Cytoplasm By similarity.
Post-translational modification	This protein undergoes a protein self splicing that involves a post-translational excision of the intervening region (intein) followed by peptide ligation. HAMAP MF_00268
Sequence similarities	Belongs to the recA family. Contains 1 DOD-type homing endonuclease domain.
