13. A homologue of the nuclear coded 49 kd subunit of bovine mitochondrial NADH-ubiquinone reductase is coded in chloroplast DNA.
The mitochondrial NADH-ubiquinone reductase (complex I) is an assembly of approximately 26 different polypeptides. In vertebrates and invertebrates, seven of its subunits are the products of genes in the mitochondrial DNA, and homologues of these genes have been found previously in the chloroplast genomes of Marchantia polymorpha and Nicotiana tabacum, altho

14. Pathological findings in homocystinuria
Pathological findings are described in four cases of a new aminoaciduria in which homocystine is excreted in the urine. All the patients were mentally retarded children. Three of them presented diagnostic features of Marfan's syndrome. Necropsy on one case and biopsy findings in the others are described. Fatty change occurs in the liver. The most striking le

15. Molecular cloning and functional analysis of a Schizosaccharomyces pombe homologue of Escherichia coli endonuclease III.
The Escherichia coli endonuclease III (Nth-Eco) protein is involved in the removal of damaged pyrimidine residues from DNA by base excision repair. It is an iron-sulphur enzyme possessing both DNA glycosylase and apurinic/apyrimidinic lyase activities. A database homology search identified an open reading frame in genomic sequences of Schizosaccharomyces pom

16. The complete nucleotide sequence of a legumin gene from pea (Pisum sativum L.).
One of several genes coding for the major pea storage protein, legumin, has been completely sequenced. The sequence covers the whole of the transcribed region, plus 5' and 3' untranscribed sequences. The predicted protein sequence starts with a signal peptide and is followed by the legumin alpha polypeptide sequence of 36. 44kd and the beta polypeptide seque

17. A role for gamma-glutamyl transpeptidase and the amino acid transport system xc- in cystine transport by a human pancreatic duct cell line.
1. The roles of the gamma-glutamyl cycle and the anionic amino acid transport system xc- in mediating L-cystine uptake were investigated in cultured human pancreatic duct PaTu 8902 cells. This cell line exhibits morphological features of normal pancreatic duct cells and expresses gamma-glutamyl transpeptidase (gamma-GT, EC 2.3.2.2), an enzyme involved in the
