title: Molecular analysis of a Penicillium chrysogenum GATA factor encoding gene (sreP) exhibiting significant homology to the Ustilago maydis urbs1 gene.
abstract: Employing a PCR-aided strategy, a Penicillium chrysogenum gene (sreP) encoding a putative GATA-transcription factor has been cloned and characterized. Comparison of the genomic and cDNA sequences revealed the presence of an open reading frame (ORF) encoding a protein of 532 amino acids (aa) which is interrupted by two introns. The deduced aa sequence of sreP reveals 50% identity to a regulator of siderophore biosynthesis (URBS1) from Ustilago maydis over a stretch of 200 aa containing two GATA-type zinc finger motifs and a Cys-rich intervening sequence. Northern blot analysis indicated two transcripts of 2.2 and 2.7 kb in approximately equivalent amount. due to two major transcription start sites.
