From a Chironomus thummi thummi genomic library we have isolated two distinct recombinant phages, CttG-1 and CttG-3, each carrying a cluster of five homologous globin genes. In addition to the previously reported nucleotide sequence of globin gene D (Antoine and Niessing, 1984) we present the chromosomal arrangement, primary structure and predicted amino acid sequence of nine globin genes. The divergently transcribed globin genes all lack introns, they encode secretory preglobins each containing a highly conserved signal peptide. The amino acid sequences deduced from the globin genes correspond to globin III and variants thereof, to globin IV, and to a novel globin, whose direct amino acid sequence has not yet been reported.
