1. Presence of the RHD pseudogene and the hybrid RHD-CE-Ds gene in Brazilians with the D-negative phenotype
The molecular basis for RHD pseudogene or RHDpsi is a 37-bp insertion in exon 4 of RHD. This insertion, found in two-thirds of D-negative Africans, appears to introduce a stop codon at position 210. The hybrid RHD-CE-Ds, where the 3' end of exon 3 and exons 4 to 8 are derived from RHCE, is associated with the VS+V- phenotype, and leads to a D-negative phenot

2. Doença de Creutzfeldt-Jakob familial com mutação pontual no codon 210 do gene da proteína priônica
A doença de Creutzfeldt-Jakob (DCJ), a mais conhecida das doenças priônicas, é usualmente esporádica, mas cerca de 15% dos casos são familiais. Sete casos de DCJ familial com mutação no codon 210 (GTT->ATT) foram relatados na literatura até o presente momento. Nós descrevemos o caso de uma mulher de 57 anos com distúrbios de marcha e demência rap

3. Mutation Patterns of the Reverse Transcriptase and Protease Genes in Human Immunodeficiency Virus Type 1-Infected Patients Undergoing Combination Therapy: Survey of 787 Sequences
The aim of the present study was to evaluate the resistance-associated mutations in 302 human immunodeficiency virus type 1 (HIV-1)-infected patients receiving combination therapy and monitored in Marseille, France, hospitals from January 1997 to June 1998. In the reverse transcriptase (RT) gene, the most frequent mutations were found at codons 215 (53%), 41

4. Significance of amino acid variation at human immunodeficiency virus type 1 reverse transcriptase residue 210 for zidovudine susceptibility.
Amino acid variation at reverse transcriptase (RT) codon 210 (generally Leu-210 to Trp [L210W], TTG-->TGG) is occasionally detected after the initiation of azidothymidine (AZT) therapy. The impact of this variation on AZT resistance and viral replication was addressed by four different approaches. The frequency and genetic background of the L210W mutation in

5. An in vivo mutation from leucine to tryptophan at position 210 in human immunodeficiency virus type 1 reverse transcriptase contributes to high-level resistance to 3'-azido-3'-deoxythymidine.
Sequencing of the reverse transcriptase (RT) region of 26 human immunodeficiency virus type 1 (HIV-1) isolates from eight patients treated with 3'-azido-3'-deoxythymidine (AZT) revealed a mutation at codon 210 from TTG (leucine) to TGG (tryptophan) exclusively in association with resistance to AZT. The mutation Trp-210 was observed in 15 of the 20 isolates p

6. Dissolution of Xylose Metabolism in Lactococcus lactis
Xylose metabolism, a variable phenotype in strains of Lactococcus lactis, was studied and evidence was obtained for the accumulation of mutations that inactivate the xyl operon. The xylose metabolism operon (xylRAB) was sequenced from three strains of lactococci. Fragments of 4.2, 4.2, and 5.4 kb that included the xyl locus were sequenced from L. lactis subs

7. Isolation and sequence of the gene for the large subunit of ribulose-1,5-bisphosphate carboxylase from the cyanobacterium Anabaena 7120
Cloned DNA probes containing genes coding for the large subunit of ribulose-1,5-bisphosphate carboxylase (rbcA) of corn and of Chlamydomonas were used to identify, by heterologous hybridization, DNA fragments from Anabaena 7120 carrying the corresponding gene sequence. The same probes were used to isolate, from a recombinant λ library, a 17-kilobase-pair Ec

8. Roles of the sequence encoding tobacco etch virus capsid protein in genome amplification: requirements for the translation process and a cis-active element.
The roles of the capsid protein (CP) and the CP coding sequence of tobacco etch potyvirus (TEV) in genome amplification were analyzed. A series of frameshift-stop codon mutations that interrupted translation of the CP coding sequence at various positions were introduced into the TEV genome. A series of 3' deletion mutants that lacked the CP coding sequence b

9. Fission yeast gene structure and recognition.
A database of 210 Schizosaccharomyces pombe DNA sequences (524,794 bp) was extracted from GenBank (release number 81.0) and examined by a number of methods in order to characterize statistical features of these sequences that might serve as signals or constraints for messenger RNA splicing. The statistical information compiled includes splicing signal (donor

10. Differential response of human cells to deletions and stop codons in the gamma(1)34.5 gene of herpes simplex virus.
Earlier studies have shown that herpes simplex virus mutants lacking the gamma(1)34.5 gene are totally avirulent on intracerebral inoculation of the virus into mice and induce premature shutoff of protein synthesis in human neuroblastoma (SK-N-SH) cells but not in Vero cells. We report the following. (i) Whereas deletion mutant R3616, lacking 1,000 bp of the

11. Nucleotide sequence of the structural gene for dUTPase of Escherichia coli K-12.
The nucleotide sequence of the dUTPase structural gene, dut, of Escherichia coli has been determined. The DNA sequence predicts a polypeptide chain of 150 amino acid residues (mol. wt. 16 006) corresponding in size and composition to the purified dUTPase subunit. In a tentative promoter region preceding the dut gene, the -35 and -10 regions are separated by

12. Gene cluster for dissimilatory nitrite reductase (nir) from Pseudomonas aeruginosa: sequencing and identification of a locus for heme d1 biosynthesis.
The primary structure of an nir gene cluster necessary for production of active dissimilatory nitrite reductase was determined from Pseudomonas aeruginosa. Seven open reading frames, designated nirDLGHJEN, were identified downstream of the previously reported nirSMCF genes. From nirS through nirN, the stop codon of one gene and the start codon of the next ge
