Geraghty, D, Peifer MA, Rubenstein I, Messing J.  1981.  The primary structure of a plant storage protein: zein. Nucleic acids research. 9:5163-74. AbstractWebsite
The protein sequence of a representative of the zeins, the major storage proteins of maize, has been derived from the nucleotide sequence of a zein cDNA clone. This cDNA was sequence both by the Maxam and Gilbert and the M13-dideoxy techniques. The nucleotide sequence encompasses the non-translated 3' terminus of the mRNA, the entire coding sequence specifying both the mature zein protein and a small signal peptide, and a portion of the non-translated 5' region. The deduced amino acid composition and the amino-terminal amino acid sequence closely resemble those derived from chemical analysis of the zein protein fraction. The data presented represent the first complete amino acid sequence of a plant storage protein.
Messing, J, Crea R, Seeburg PH.  1981.  A system for shotgun DNA sequencing. Nucleic acids research. 9:309-21. AbstractWebsite
A multipurpose cloning site has been introduced into the gene for beta-galactosidase (beta-D-galactosidegalactohydrolase, EC 3.21.23) on the single-stranded DNA phage M13mp2 (Gronenborn, B. and Messing, J., (1978) Nature 272, 375-377) with the use of synthetic DNA. The site contributes 14 additional codons and does not affect the ability of the lac gene product to undergo intracistronic complementation. Two restriction endonuclease cleavage sites in the viral gene II were removed by single base-pair mutations. Using the new phage M13mp7, DNA fragments generated by cleavage with a variety of different restriction endonucleases can be cloned directly. The nucleotide sequences of the cloned DNAs can be determined rapidly by DNA synthesis using chain terminators and a synthetic oligonucleotide primer complementary to 15 bases preceeding the new array of restriction sites.

A primer for DNA sequencing by the chain-termination method in the M13mp2 cloning system was constructed and amplified. The primer was isolated as an EcoRI/AluI restriction fragment. After conversion of the AluI end into an EcoRI end the fragment was cloned in pBR325 from which it can be recovered by cleavage with EcoRI. The primer hybridizes to the single-stranded DNA of the mature M13mp2 phage next to the site of insertion thereby directing DNA synthesis along the inserted DNA.

Proceedings of the National Academy of Sciences of the United States of America. 74:3642-6. AbstractWebsite
A HindII restriction fragment comprising the Escherichia coli lac regulatory region and the genetic information for the alpha peptide of beta-galactosidase (beta-D-galactosidegalactohydrolase, EC. 3.2.1.23) has been inserted into 1 of the 10 Bsu I cleavage sites of M13 by blunt end ligation. A stable hybrid phage was isolated and identified by its ability to complement the lac alpha function. Further characterization of the hybrid phage includes retransformation studies, agarose gel electrophoresis, DNA-DNA hybridization, and heteroduplex mapping. The insertion point has been localized at 0.083 map unit on thewild-type circular map-i.e., within the intergenic region. The results prove that part of the intergenic region is nonessential and that the phage can be used as a cloning vehicle.
