UniProtKB - P07394 (MATA_BPGA)
Protein
Maturation protein A
Gene
A
Organism
Enterobacteria phage GA (Bacteriophage GA)
Status
Functioni
The maturation protein is required for the typical attachment of the phage to the side of the bacterial pili. Binds to sequences located toward each end of the genome, hence circularizing it. The RNA genome-maturation protein A complex is released from the capsid upon host receptor binding. Maturation protein A enters the cell along with the viral RNA.
