DNA sequences and structural homologies of the replication origins of lambdoid bacteriophages.
The DNA sequences for the origins of replication of the lambdoid bacteriophages phi80, 434, phi21, and lambdaimm21 (identical to phi21) have been determined and compared to the lambda structure. Two presumptive elaborate binding sites for two initiator proteins have been identified in their outer sections, while a replicational primer start site seems to be located in their centres.
