UniProtKB - O64306 (MATA2_BPMX1)
Protein
Maturation protein A2
Gene
A
Organism
Escherichia phage Qbeta
Status
Functioni
Induces host cell lysis. Inhibits host MurA activity thereby blocking the synthesis of murein precursors necessary for the host cell wall biosynthesis. May be responsible for the attachment to the host pilus.
