Abstract
The product of the saf gene of Streptomyces griseus ATCC10137 mediated an increase in the production of several extracellular enzymes and retarded the formation of pigments and spores in Streptomyces [Daza et al., Mol. Gen. Genet. 222 (1990) 384-392]. A promoter upstream from saf was identified by subcloning a DNA fragment in the promoter probe pIJ486. Using the Escherichia coli-Brevibacterium lactofermentum promoter-probe shuttle vector, pULMJ51, we determined that the saf promoter region is also active in E. coli. The transcription start points (tsp) of the saf promoter in Streptomyces and E. coli have been determined using high-resolution S1 mapping. The tsp are at the same position in both microorganisms. Expression from the saf promoter region was negatively regulated by phosphate in Streptomyces, but not in E. coli. The amplification of the saf promoter lacking the saf coding region did not increase the production of extracellular enzymes and did not reduce sporulation or pigmentation in Streptomyces (i.e., it does not titrate out a putative repressor of the genes encoding extracellular enzymes). Several structural features of the saf promoter region and saf mRNA are studied in relation to the regulation of the saf gene expression.

Abstract
Various constructions of human haptoglobin (Hp) cDNA coding either for the complete alpha 2FS beta precursor protein or only for the beta subunit have been placed under the control of the lambda PR promoter in the bacterial expression vector pCQV2 (Queen, 1983). In addition to the expected 45,000 dalton polypeptide synthesized after induction of the PR promoter, the complete alpha 2FS beta constructions constitutively express a smaller polypeptide of approximately 30,000 dalton corresponding to a truncated Hp protein. Computer analysis of the HpcDNA revealed the presence of two strong potential bacterial promoters (alpha 2 PF and alpha 2 PS) located in the duplicated alpha 2FS sequence. Both Hp promoter signals are followed by potential mRNA start sites and ribosome binding sites at a compatible distance from initiation codons. In addition, the Hp alpha 2 cDNA sequence, when fused upstream to the cDNA coding for alpha 1-antitrypsin, constitutively promotes in vivo the efficient expression of an hybrid protein specifically recognized by antibodies raised against alpha 1-antitrypsin or haptoglobin.

Abstract
Following the construction of a series of pSV2-cat derived plasmids containing the chloramphenicol acetyltransferase (CAT) gene under the control of a eukaryotic trout protamine promoter, it was noted that Escherichia coli, transformed with these plasmids, developed resistance to chloramphenicol (CM). This result suggested that the eukaryotic trout protamine promoter possessed significant prokaryotic promoter activity. Modification of the trout protamine promoter region by removing the region containing the eukaryotic Goldberg-Hogness box in the plasmid p525-cat increased the expression of the CAT gene almost to the wild-type level and conferred strong CM resistance. Sequence comparisons of the plasmid series indicate that prokaryotic promoter elements are present in the trout protamine promoter and that their similarity to the prokaryotic promoter consensus sequences and the distance between the two elements is more favourable in p525-cat, the plasmid which confers the greatest CM resistance.

Abstract
Prokaryotic gene control signals can be isolated, compared, and characterized by precise fusion in vitro to the Escherichia coli galactokinase gene (galK), which provides both a simple assay and genetic selection. This recombinant galK fusion vector system was applied to the study of promoters and terminators recognized by the Escherichia coli RNA polymerase. Three promoters created by mutation from DNA sequences having no promoter function were characterized. Mutations that inactivate promoter function were selected, structurally defined, and functionally analyzed. Similarly, transcription termination was examined, and mutations affecting terminator function were isolated and characterized.

Abstract
RNA polymerase holoenzyme from Micrococcus luteus synthesizes in vitro a run-off transcript of 85 nucleotides from a DNA fragment containing part of gene E of bacteriophage phi X174. This RNA starts with GTP as the 5' terminus 18 nucleotides downstream from the start of gene E on the viral (+)strand. Transcription does not occur when the fragment is cleaved 36 nucleotides upstream of the initiation site. No transcript is obtained with RNA polymerase core or holoenzyme from Escherichia coli. Other DNA fragments containing the three major E. coli promoters of phi X174 are transcribed by both enzymes although much less efficiently by M. luteus RNA polymerase. When subunit sigma in E. coli RNA polymerase is replaced by sigma from M. luteus the resulting hybrid enzyme actively transcribes the DNA fragment containing the inner region of gene D with formation of the same run-off transcript which is obtained with M. luteus holoenzyme. In the presence of sigma from E. coli this RNA is not synthesized. The hybrid enzyme also transcribes a DNA fragment containing the gene A promoter of phi X174 with even higher efficiency than RNA polymerase holoenzyme from E. coli.

Abstract
We have isolated a unique 35 base pair region of avian tumor virus DNA that binds specifically to Escherichia coli RNA polymerase holoenzyme. Studies with various size classes of viral DNA coupled with restriction enzyme mapping data indicate that the binding site is located in the large terminal repeat of the viral genome and is within the first 50 nucleotides of the heteropolymeric region corresponding to the 3'-end of the virion RNA.

Abstract
The primary structure of the SmaI-K fragment of adenovirus type 2 (Ad2) DNA has been determined. This region includes one of the origins of DNA replication (Winnacker, 1978; Sussenbach and Kuijk, 1978). A leader sequence for an early mRNA in region 4 (Berk and Sharp, 1977; 1978) has also been mapped in this region. The comparison of the primary structure of this region in Ad2 DNA with the corresponding region in Ad5 DNA shows a remarkable homology which may be significant in view of the fact that Ad2 and Ad5 DNAs can interchangeably function in the in vitro replication system of Challberg and Kelly (1979).

Abstract
The influence of ionic strength on transcription of polyoma DNA by Escherichia coli RNA polymerase was investigated. At 0.15 M KCl, transcription was highly symmetrical and, due to the lack of reinitiation, a limited extent of RNA synthesis was observed. When the concentration of KCl was raised to 0.45 M, the affinity of the enzyme for its template, as well as its apparent affinity for ribonucleoside triphosphates, was reduced. Under optimal conditions, the rate and extent of RNA synthesis at 0.45 M KCl were greater than at 0.15 M KCl, and transcription was mostly asymmetric. Binding and initiation sites at both ionic strengths were identified; at 0.15 M KCl, transcription was initiated from two major sites, located at 0.99 and 0.06 map unit, whereas at 0.45 M KCl, a unique initiation site, at 0.99 map unit, was selected by RNA polymerase.

Abstract
The adenovirus type 2-simian virus 40 (SV40) hybrid virus Ad2+ND1 dp2 (E. Lukanidin, manuscript in preparation) specified two proteins (molecular weights, 24,000 and 23,000) that are, in part, products of an insertion of SV40 early DNA sequences. This was demonstrated by translation in vitro from viral mRNA that had been selected by hybridization to SV40 DNA. These two phosphorylated, nonvirion proteins were produced late in infection in amounts similar to adenovirus 2 structural proteins and were closely related to each other in tryptic peptide composition. The portion of SV40 DNA (map units 0.17 to 0.22 on the SV40 genome) coding for these proteins was joined to sequences coding for the amino-terminal part of the adenovirus type 2 structural protein IV (fiber). The Ad2+ND1 dp2 23,000- and 24,000-molecular-weight proteins were hybrid polypeptides, with about two-thirds of their tryptic peptides contributed by the fiber protein and the remainder contributed by SV40 T-antigen. They shared with T-antigen (molecular weight, 96,000) a carboxy-terminal proline-rich tryptic peptide. Together, the tryptic peptide composition of these proteins and the known SV40 DNA sequences suggested the reading frame for the translation of T-antigen. The carboxy terminus for T-anigen would then be located on the SV40 genome map next to the TAA terminator triplet at position 0.175, 910 bases away from the cleavage site of the restriction endonuclease EcoRI. Seven host range mutants from Ad2+ND1 dp2 were isolated that had lost the capacity to propagate on monkey cells. They did not induce detectable levels of the hybrid proteins. Three of these mutants had lost the SV40 DNA insertion that codes in part for these proteins. Thus, in analogy to the Ad2+ND1 30,000-molecular-weight protein, the presence of these proteins correlates with the presence of the helper function for adenovirus replication on monkey cells.

Abstract
We report the isolation of four independently selected mutations (scs) in the c17 promoter of phage lambda that reduce or eliminate the promoter activity. The c17 promoter is not normally present in lambda, and has been shown to be generated by a tandem duplication which creates a "Pribnow Box," a heptamer sequence implicated in promoter activity. This sequence is located upstream from the site of transcription initiation and is present, with some variation, in all promoters whose sequences have been determined. Analysis of the c17 duplications carrying the scs mutations reveals that three of these mutants carry single base-pair changes in the most highly conserved base pairs of the Pribnow Box and that the other mutation is a reversion to the wild type sequence in this region (i.e., a loss of the duplicated base pairs).

Abstract
Restriction fragments of T7 DNA which selectively bind E. coli RNA polymerase have been identified. These include fragments located close to the beginning of gene 1 where according to Minkley and Pribnow (1973) there is a promoter called C. The smallest fragment from this region which binds RNA polymerase has been sequenced. It contains a promoter-like sequence, at an appropriate distance from the sequence TACA which Minkley and Pribnow suggested should lie at the initiation site of C. RNA synthesised in vitro from these fragments has been sequenced. The RNA sequence corresponds to the sequence to the right of the C promoter. The C promoter differs significantly from the A1 A2 and A3 promoters in sequence. Its structure and position suggest it plays a role in T7 infection.

Abstract
I have determined the nucleotide sequences of the three major early promoters of bacteriophage T7 (A1, A2, A3). The sequences confirm the two main homologies found between other known promoters for E. coli RNA polymerase (nucleoside triphosphate:RNA nucleotidyl transferase, E.C. 2. 7. 7. 6). In particular, all three T7 promoters show a very good match with the -35 region homology; the A2 and A3 promoters share a 17 basepair sequence in this region. On the other hand, the match with the Pribnow Box homology is much less pronounced and different for each T7 promoter.

Abstract
It is proposed that the biotin anabolic operon in Escherichia coli is transcribed divergently from two partially overlapping face-to-face promoters. A mutation that increases transcription in vivo creates an additional promoter in vitro. The putative operator contains an imperfect palindromic sequence that partially overlaps the promoters. The regulatory and genetic implications of these findings are discussed.

A novel computer procedure has been used to search for homology among 17 known procaryotic promoter sequences. A model sequence, :formula: (see text), is compatible with the properties of all known promoter and operator mutations, predicts base positions for the initiation of RNA synthesis coinciding with those determined experimentally, is compatible with current models for the regulation of transcription, suggests that RNA polymerase could recognize the DNA double helix firstly in the B conformation then in the A.

Abstract
The number and the distribution of the sites of Escherichia coli DNA that form stable complexes with the homologous RNA polymerase (class A sites according to Hinkle and Chamberlin [3]) have been investigated. Almost all the DNA can bind RNA polymerase, even when fragmented at short (undergenic) size; this general non-promoter-specific binding is highly labile and is not temperature-dependent. The range of RNA polymerase/DNA ratios that give rise to the stable temperature-dependent complexes was examined. The amount and the distribution of class A complexes were studied analysing the dissociation of complexes formed by RNA polymerase on DNA fragments of various length. The E. coli genome appears to form 3.8 X 10(3) stable complexes; the majority of these complexes shows a short-range distribution (800-1200 base pairs). The rest is more widely spaced (1200-6000 base pairs).

Abstract
The restriction fragment Hind-G represents 7.0% of the simian virus 40 (SV40) genome. The information present in fragment Hind-G is expressed as part of the major, late 16-S messenger RNA. The complete nucleotide sequence of the fragment Hind-G has now been determined by application of the procedure of Maxam and Gilbert [Proc. Natl Acad. Sci. U.S.A. (1977) 74, 560-564]. It contains 369 nucleotide base pairs. On the basis of the termination code words in the strand with the same polarity as the late mRNA, two illegitimate reading frames can be defined. Therefore the third, open frame must code for the carboxyl terminal part of the VP1 protein. It terminates within fragment Hind-G with a TGA signal. This stop codon is followed by a non-translated region of the mRNA of about 83 nucleotides. The latter contains the sequence A-A-U-A-A-A, common to all other eukaryotic mRNA molecules so far studied. The Hind-G fragment also contains sequences which presumably play a role in the synthesis, processing and/or expression of early mRNA; these aspects are discussed in the following paper.

Abstract
The nucleotide sequence of SV40 DNA was determined, and the sequence was correlated with known genes of the virus and with the structure of viral messenger RNA's. There is a limited overlap of the coding regions for structural proteins and a complex pattern of leader sequences at the 5' end of late messenger RNA. The sequence of the early region is consistent with recent proposals that the large early polypeptide of SV40 is encoded in noncontinguous segments of DNA.

Abstract
The nucleotide sequence around the origin of replication in DNA of mouse polyoma virus was determined by 32P labeling of the 3' terminus of the Hap II-5/Alu I-1 DNA fragment, with the use of DNA polymerase. The result coincided with our previous report on the 32P labeling, with the use of polynucleotide kinase, of the 5' terminus of the Hap II-5/Hha I-1 DNA fragment, which corresponds to the large part of the present fragment, Hap II-5/Alu I-1. A symmetrical (A+T)-rich region containing a five-A stretch (or a five-T stretch) was flanked by two small regions with a 2-fold rotational axis of symmetry. On comparison of the sequence near the replication origin of polyoma DNA with that in the corresponding region of simian virus 40 DNA, which was included in the EcoRI-G fragment sequenced by Weissman's group (Subramanian K.N., Dahr, R. & Weissman, S. M. (1977) J. Biol. Chem. 252, 355--367), a considerable similarity was detected. Several possible common sequences for important biological activities such as the starting of DNA replication and RNA synthesis were suggested.

Abstract
Regulatory regions in DNA which have been sequenced have generally been found to contain one or more axes of two-fold rotational symmetry. If this symmetry is to be maintained in the helical sequence, the axis of rotation must be aligned with one of the two dyad axes of the helix. This is equivalent to saying that the rotational symmetry of the sequence can only be seen from certain viewing points in a circuit about the helix. More surprising is the fact that new symmetrical sequence arrangements can be seen at +/- 36 degrees, +/- 72 degrees, +/- 108 degrees, and +/- 144 degrees relative to the point at which the rotational symmetry is seen. This "amplification" of symmetry suggests a three-dimensional approach to sequence analysis. A specific reading frame, suggested by the geometry of the helix, is examined with regard to its elucidation of intra- and inter-sequence homologies. Two sequences are thus identified as being recurrent in a number of different regulatory sequences.

Abstract
The in vitro binding of the Escherichia coli RNA polymerase (nucleosidetriphosphate:RNA nucleotidyltransferase; EC 2.7.7.6) to fragments of lambdaplac5 DNA generated by restriction endonucleases HindII and HindIII has been studied by a filter binding technique. The results are consistent with RNA polymerase binding at p(R)', the INT promoter (p(I)), several sites in the b2 region, the mis promoter, the oop promoter (or p(O)), and p(rm). Binding was also observed on some fragments that are not known to contain active promoters, including the fragment from the cIII-t(L) region. Some of these binding reactions might also be explained by interaction of RNA polymerase with termination sites. Additional polymerase binding sites have been detected by examining which HindII and HindIII sites were not cleaved when digestion was performed after RNA polymerase had been bound to the DNA. This technique revealed polymerase binding at p(L), at p(R), at a site between R and cos, and at a site at the junction of the gamma and cIII-t(L) fragments. A comparison of the location of polymerase binding fragments with the partial denaturation map of the lambda genome indicates that RNA polymerase binding sites are located within A-T rich regions. It is suggested that RNA polymerase binding is a function both of specific sequences (where recognition occurs) and of the base composition of the surrounding regions (which affects the stability of the helix at the specific site).

Abstract
Although human adenoviruses grow poorly in monkey cells, this defect can be overcome either by coinfection of cells with simian virus 40 (SV40) or by insertion of the relevant portion of the SV40 genome into the adenovirus genome to form an adenovirus-SV40 hybrid virus. The nondefective adenovirus-2-SV40 hybrid virus, Ad2+ND1, contains an insertion of 17% of the SV40 genome, which codes for at least part of a 30,000 dalton protein. A set of Ad2+ND1 host-range mutants that have lost the ability to grow in monkey cells and behave as point mutants fail to synthesize the 30,000 dalton ND1 protein. Translation in vitro of SV40-specific mRNA from mutant-infected cells produces unique short polypeptides instead of the 30,000 dalton protein. Here we show that this set of host-range mutants includes both ochre and amber nonsense mutations. When the SV40-specific mRNA from the host-range mutants is translated in vitro to produce the polypeptide fragments, yeast suppressor tRNA can partially restore synthesis of wild-type-size 30,000 dalton protein. By this assay, one mutant is ochre and two are amber.

Abstract
The HindII + III restriction enzyme fragmentation pattern of various lambda-phi80trp deoxyribonucleic acid molecules is presented. An analysis of deoxyribonucleic acid molecules carrying deletions ending within the trp regulatory elements and a deoxyribonucleic acid molecule carrying a deletion within trpE indicates that a fragment of 8.3 X 10(5) daltons contains at least part of the trp promoter, the entire trp leader region, and part of the trpE gene. The observation that ribonucleic acid polymerase, when present in the HindII + III digestion mixture, results in the fusion of this 8.3 X 10(5)-dalton fragment to the preceding bacterial fragment suggests that HindII + III cuts within trpP.

Abstract
The nucleotide sequence of 70 base pairs (bp) around 0.545 map units (Alu I C and B junction) of the genome from the single Eco RI cleavage site within SV40 DNA is presented. The mRNA transcribed from the early strand template from this stretch contains two copies of the nonsense triplet UAA in each of the three reading frames. Thus at least 25% of the early region of SV40 DNA does not code for the SV40 "A" protein, and the viral contribution to events in the lytic cycle and transformation may be more complex than is generally appreciated.

Abstract
The promoter for the major coat protein gene of bacteriophage fd contains a unique sequence. TATAAT, in the non-transcribed region corresponding to the Pribnow box. A R-Hha I cleavage site which destroys functions is located five pairs upstream from the TATAAT sequence (fifteen base pairs upstream from the RNA initiation site). The promoter was cleaved into two fragments by R-Hha I and each promoter fragment was joined to DNA fragments derived from other regions. Ligation of the TATAAT-containing fragment to any of the DNA fragments examined resulted in recovery of promoter function. The results suggest for this type of promoter that no unique sequence is necessary upstream from the R-Hha I cleavage site although a contiguous DNA chain must be present in this area.

Abstract
Sequences with 2-fold axes of symmetry have been detected and mapped on the simian virus 40 (SV40) genome by their ability to form hairpin turns in single-stranded SV40 DNA. Supercoiled SV40 DNA (SV40 I) was digested with restriction enzymes EcoRI and HpaII. The resulting linear DNA molecules with lengths of the complete SV40 genome were then denatured and photochemically reacted with 4,5',8-trimethylpsoralen (trioxsalen) at 16.0 +/- 0.5 degrees and different ionic strengths. Secondary structures on the single-stranded SV40 DNA were crosslinked and their positions analyzed by electron microscopy. There were no observable hairpin turns on the denatured SV40 DNA when it was photoreacted in 1 mM Tris-HCl/0.1 mM EDTA at pH 7.0. In 20 mM NaCl, one specific hairpin turn was detected at 0.17 +/- 0.02 map units on the map of EcoRI-digested SV40 DNA, where the 3' ends of early 19S mRNA, late 19S mRNA, and 16S mRNA of SV40 have been mapped. In 30 mM NaCl there are five more major hairpin turns besides the most stable one. The centers of four of these specific hairpin turns were mapped at 0.26 +/- 0.02, 0.68 +/- 0.03, 0.84 +/- 0.02, and 0.94 +/- 0.01 units on the map of EcoRI-digested SV40. The fifth one is at or near the unique EcoRI cleavage site on SV40 DNA. The possible functions of these sequences are discussed in terms of the nature of the promoter sites, the replication origin, the processing of RNA precursors, and regulation at the translational level.

Abstract
The nucleotide sequence of the region of DNA of simian virus 40 extending from 0.595 to 0.790 map unit has been derived. The sequence includes the DNA complementary to the 5' end of early mRNA and to the 5' end of some of the forms of late RNA. Because there are termination codons in all three phases in early and late RNA, there is a sequence of almost 800 nucleotides of simian virus 40 DNA that probably does not code for known viral proteins. The sequence spans the 5' end of the early mRNA at 0.67 map unit and overlaps a species of late RNA whose 5' end is at 0.65 map unit and whose 3' end is at 0.77 map unit. This RNA is retained on oligo(dT)-cellulose columns in high salt concentrations. Analysis of the sequence of late strand RNA suggests that this RNA is not covalently linked to the mRNA that encodes structural proteins. There is another species of late RNA of simian virus 40 whose 5' end is at 0.775 map unit. The nucleotide sequence of this region of simian virus 40 DNA contains several examples of repeated sequences, most of which are located in DNA that does not encode known peptides. These may be analogous to the reiterated sequences that have been described in animal cell DNA.

Abstract
The sequences corresponding to the 18S and 28S rRNAs have been mapped within a cloned 17 kilobase (kb) fragment formed by Eco R1 cleavage of Drosophila melanogaster rDNA. This fragment, Dm103, represents the longer of two major types of repeating units that are present in the rDNA of this fly, and was cloned as a hybrid plasmid, pDm103, consisting of Dm103 inserted at the Eco R1 site of the pSC101 vector (Glover et al., 1975). Mapping of the 18S and 28S rDNA in Dm103 was accomplished by quantitative determination of the amount of these rDNAs in each member of an ordered set of restriction fragments obtained by Hind III and Eco R1 ccleavage of pDm103. The amounts of 18S and 28S rDNAs were determined by hybridization of the rRNAs to fragments that were purified by cloning, and an unambiguous order of the fragments within pDm103 was established by heteroduplex mapping and from the stoichiometry of the fragment lengths. The resulting map revealed that the 4 kb of 28S rDNA within the long repeating unit represented by Dm103 is divided into two blocks that are separated by 5.4 kb of DNA of unknown function. It is this unusual arrangement of the 28S rDNA that distinguishes the long repeating units (17 kb) from the short units (11.5) kb), whose 4 kb of 28S rDna is confined to a single block, as is shown in the accompanying paper (White and Hogness, 1977). The remainder of the DNA in this long unit appears to be typically arranged, with the 2 kb of 18S rDNA confined to a single block that is separated by about 1 kb from the closest block of 28S rDNA.

Abstract
We have derived the nucleotide sequence of a segment of the operator-promoter region of the galactose operon of E. coli, by using a variety of DNA sequencing analyses. We have previously reported the sequence of the 5' terminal portion of gal mRNA [Musso, R. E., de Crombrugghe, B., Pastan, I., Sklar, J., Yot, P. & Weissman, S. (1974) Proc. Natl. Acad. Sci. USA 71, 4940-4944] and of the 59 base pairs preceding the startpoint of gal transcription (J. Sklar, S. Weissman, R. Musso, R. Di Lauro, & B. de Crombrugghe, submitted). In conjunction with those results, the present data provide the sequence of the gal operator-promoter region. This sequence is compared with similar sequences in other promoters and operators. Tentative mechanisms for the regulation of the galactose operon are discussed.

Abstract
This review provides a comprehensive account of the current status of the biology and biochemistry of restriction endonucleases. Both Class I and Class II restriction endonucleases will be considered. However, emphasis will be placed on the Class II group, which recognizes and cleaves a specific duplex DNA sequence. Their occurrence, purification, and characterization is discussed in detail. The characterization includes physical mapping information and determination of recognition sequences. In addition to detailed discussions of the biochemical properties of the enzymes, considerable attention is paid to the uses of these enzymes as tools for research in molecular biology. These uses include physical mapping of genomes and their transcripts, genetic analysis (marker rescue, etc.), DNA sequence analysis, analysis of complex genomes, and genetic engineering. Specific examples of each use are outlined. Practical aspects of both the isolation and use of the restriction endonucleases form the major theme of this review.
