Organism

Methanospirillum hungatei (strain JF-1 / DSM 864) [Complete proteome] [HAMAP]

Taxonomic identifier

323259 [NCBI]

Taxonomic lineage

Archaea › Euryarchaeota › Methanomicrobia › Methanomicrobiales › Methanospirillaceae › Methanospirillum

Protein attributes

Sequence length	1286 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Possesses two activities: a DNA synthesis (polymerase) and an exonucleolytic activity that degrades single stranded DNA in the 3'- to 5'-direction. Has a template-primer preference which is characteristic of a replicative DNA polymerase By similarity.
Catalytic activity	Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). HAMAP MF_00324 Degradation of single-stranded DNA. It acts progressively in a 3'- to 5'-direction, releasing nucleoside 5'-phosphates. HAMAP MF_00324
Subunit structure	Heterodimer of a large subunit and a small subunit 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 Potential.
Sequence similarities	Belongs to the archaeal DNA polymerase II family.
