Sites and gene products involved in lambdoid phage DNA packaging.
21 is a temperate lambdoid coliphage, and the genes that encode the head proteins of lambda and 21 are descended from a common ancestral bacteriophage. The sequencing of terminase genes 1 and 2 of 21 was completed, along with that of a segment at the right end of 21 DNA that includes the R4 sequence. The R4 sequence, a site that is likely involved in termination of DNA packaging, was found to b...
متن کاملA phi 80 function inhibitory for growth of lambdoid phage in him mutants of Escherichia coli deficient in integration host factor. I. Genetic analysis of the Rha phenotype.
Bacteriophage phi 80 and lambda-phi 80 hybrid phage of the type lambda (QSR)80, in which the rightmost 10% of the lambda genome is replaced by corresponding phi 80 material, are unable to grow lytically in himA and hip/himD mutants of Escherichia coli K12 at 32 degrees. The genetic element responsible for the growth defect, rha, has been mapped to the (QSR)80 region and was located more precise...
متن کاملA phi 80 function inhibitory for growth of lambdoid phage in him mutants of Escherichia coli deficient in integration host factor. II. Physiological analysis of the abortive infection.
Derivatives of phage lambda with the rightmost 3% of the genome (the QSR region) from the related phage phi 80 fail to grow at low temperatures (e.g., 32 degrees) in Escherichia coli hosts deficient in either protein component of IHF (integration host factor), the products of the himA and hip/himD genes. The abortive infection of lambda (QSR)80 in mutants defective for IHF was studied in detail...
متن کاملThe pinholin of lambdoid phage 21: control of lysis by membrane depolarization.
The phage 21 holin, S(21), forms small membrane holes that depolarize the membrane and is designated as a pinholin, as opposed to large-hole-forming holins, like S(lambda). Pinholins require secreted SAR endolysins, a pairing that may represent an intermediate in the evolution of canonical holin-endolysin systems.
متن کاملAssembly and function of the lambdoid bacteriophage tail: observations from phi 80-lambda host-range phenotypic mixing.
The host-range proteins of lambda and phi80, while differing sharply in host-receptor specificity and in sensitivity to phage-killing antiserum, can be assembled into functional phage tail structures of mixed composition.
