Recently, M13 bacteriophage has started to be widely used as a functional nanomaterial for various electrical, chemical, or optical applications, such as battery components, photovoltaic cells, sensors, and optics. In addition, the use of M13 bacteriophage has expanded into novel research, such as exciton transporting. In these applications, the versatility of M13 phage is a result of its nonto...

M13 viral strand synthesis is initiated by nicking of the viral strand of the duplex replicative form by the M13 gene II initiator protein at a specific site within a sequence of about 40 base pairs having dyad symmetry. Efficient replication of the M13 viral strand also requires the presence of an adjacent sequence of ca. 100 base pairs. Together these sequences constitute the minimal origin f...

The replication origins of viral and complementary strands of bacteriophage M13 DNA are contained within a 507-nucleotide intergenic region of the viral genome. Chimeric plasmids have been constructed by inserting restriction endonuclease fragments of the M13 intergenic region into the plasmid pBR322. Replication of these hybrid plasmids, under conditions not permissive for the plasmid replicon...

Using simple design and selective pressure, we have evolved an artificial M13 bacteriophage coat protein. M13 coat proteins first reside in the bacterial inner membrane and subsequently surround the DNA core of the assembled virus. The artificial coat protein (ACP) was designed and evolved to mimic both functions of the natural M13 coat proteins, but with an inverted orientation. ACP is a non-f...

Superhelical covalently closed circular replicative form DNA (RF I) of coliphage M13 appears as a relaxed molecule that has a base-unpaired region in the form of a bubble (100 to 200 base pairs long) seen in electron micrographs when spread in the presence of formaldehyde and formamide or after pretreatment with glyoxal. S1 endonuclease, specific for single-stranded DNA, converts superhelical M...

In this work, we report a new method to reversibly immobilize proteins to a surface in a functionally active orientation directly from cell lysate by employing a fusion protein consisting of a thermal-responsive elastin (ELP) domain as the surface anchor and a calcium-responsive calmodulin (CalM) domain for protein capturing. Incorporation of an M13 tag into recombinant proteins enables not onl...

The major coat protein (gene 8 product) of coliphage M13 is an integral protein of the host cell cytoplasmic membrane prior to virus assembly. It is synthesized as a precursor, termed procoat, with an extra 23 NH2terminal residues. We have studied the synthesis, assembly, and processing of procoat protein by amino acid pulse-labeling E. coli which are infected by either M13 or by M13 with amber...
