Organism

Synechocystis sp. (strain PCC 6803) [Complete proteome] [HAMAP]

Taxonomic identifier

1148 [NCBI]

Taxonomic lineage

Bacteria › Cyanobacteria › Chroococcales › Synechocystis

Protein attributes

Sequence length	831 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Recognizes a specific hairpin sequence on phiX ssDNA. This structure is then recognized and bound by proteins priB and priC. Formation of the primosome proceeds with the subsequent actions of dnaB, dnaC, dnaT and primase. PriA then functions as a helicase within the primosome By similarity.
Sequence similarities	Belongs to the helicase family. PriA subfamily. Contains 1 helicase ATP-binding domain. Contains 1 helicase C-terminal domain.
