Names and origin

Protein namesRecommended name:
Probable translation initiation factor IF-2

Cleaved into the following chain:

  1. Mja infB intein
    Alternative name(s):
    Mja IF2 intein
Gene names
Name:infB
Ordered Locus Names:MJ0262
OrganismMethanocaldococcus jannaschii (strain ATCC 43067 / DSM 2661 / JAL-1 / JCM 10045 / NBRC 100440) (Methanococcus jannaschii)
Taxonomic identifier243232 [NCBI]
Taxonomic lineageArchaea › Euryarchaeota › Methanococci › Methanococcales › Methanocaldococcaceae › Methanocaldococcus

Protein attributes

Sequence length1155 AA.
Sequence statusComplete.
Sequence processingThe displayed sequence is further processed into a mature form.
Protein existenceInferred from homology

General annotation (Comments)

Function

Function in general translation initiation by promoting the binding of the formylmethionine-tRNA to ribosomes. Seems to function along with eIF-2 By similarity. HAMAP MF_00100_A

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 Potential. HAMAP MF_00100_A

Miscellaneous

The intein interrupts the GTP-binding site. HAMAP MF_00100_A

Sequence similarities

Belongs to the IF-2 family.

Contains 1 DOD-type homing endonuclease domain.
