FIG. 2.

catA regulatory and coding sequences present in the catA::lacZ gene fusion included in pREN8. Arrows indicate transcription initiation sites determined by primer extension previously (27) or in this work (∗). A black dot indicates the 5′ end of catA cDNA clone C1g07a1.r2 reported in the A. nidulans expressed sequence tag database (29a). catA putative coding sequences are shown in boldface; a putative TATA box is underlined (27). The first codon from E. coli lacZ containing plasmid pRA42 (6) is boxed.
