Abstract: We report the isolation and analysis of human genomic DNA clones spanning about 100 kb of the X chromosome and comprising the entire gene coding for the enzyme glucose 6-phosphate dehydrogenase (G6PD). The G6PD gene is 18 kb long and consists of 13 exons: the protein-coding region is divided into 12 segments ranging in size from 12 to 236 bp; an intron is present in the 5' untranslated region. Mature G6PD mRNA has a single polyadenylation site in HeLa cells. The major 5' end of mature G6PD mRNA in several cell lines is located 177 bp upstream of the translation initiating codon; longer mRNA molecules extending further in the 5' direction could be identified by S1 mapping and by comparing genomic and cDNA sequences. The DNA sequence around the major mRNA start is very GC rich; as to putative transcription regulatory sequences, a non-canonical TATA box and 9 CCGCCC elements are present, but no CAAT element could be identified. The genomic DNA we have isolated includes another ubiquitously transcribed region, provisionally named the GdX gene. Although the function of GdX is as yet unknown, we have established that this gene is located about 40 kb downstream of G6PD and is transcribed in the same direction. A comparative analysis of the promoter region of G6PD and 10 other housekeeping enzyme genes has confirmed the presence of a number of common features. In particular, in the eight cases in which a 'TATA' box is present, a conserved sequence of 25 bp is seen immediately downstream.

Abstract: The X-chromosome-linked glucose-6-phosphate dehydrogenase (D-glucose-6-phosphate:NADP+ oxidoreductase, EC 1.1.1.49) of humans and other mammals consists of a subunit with a molecular weight of about 58,000. The enzyme plays a key role in the generation of NADPH, particularly in matured erythrocytes, and the genetic deficiency of the enzyme is associated with chronic and drug- or food-induced hemolytic anemia in humans. The enzyme was purified to homogeneity from human erythrocytes. The complete amino acid sequence of the subunit, consisting of 531 amino acid residues, was determined by automated and manual Edman degradation of tryptic, chymotryptic, thermolytic, and cyanogen bromide peptides obtained from the enzyme. Based on the amino acid sequence data thus obtained, a 41-mer oligonucleotide with unique sequence was prepared. Two cDNA libraries constructed in phage lambda gt11--i.e., a human liver cDNA library and a human hepatoma Li-7 cDNA library--were screened with the synthetic nucleotide probe. Two positive clones, lambda G6PD-19 and lambda G6PD-25, were obtained from the hepatoma library. lambda G6PD-19 contained an insertion of 2.0 kilobase pairs (kbp), and encoded 204 amino acid residues that were completely compatible with the COOH-terminal portion of the enzyme. The insertion of the clone had a 3' noncoding region of 1.36 kbp. The other clone, lambda G6PD-25, had an insertion of 1.8 kbp and encoded 362 amino acid residues of G6PD. Southern blot analysis of DNA samples obtained from cells with and without the human X chromosome indicated that the cDNA hybridizes with a sequence in the X chromosome.
