title: Characterization of the mnp2 gene encoding manganese peroxidase isozyme 2 from the basidiomycete Phanerochaete chrysosporium.
abstract: The nucleotide (nt) sequence of a gene (mnp2) encoding manganese peroxidase isozyme 2 (MnP-2) from Phanerochaete chrysosporium was determined. The sequence of 3297 bp includes 1287 bp of 5'-flanking sequence and 490 bp 3' to the stop codon. Comparison of cDNA and genomic sequences indicates seven introns varying in size from 50-55 bp. The 5' upstream region of the mnp2 gene contains a TATAA element, three inverted CCAAT elements (ATTGG), six putative heat-shock elements (HSE) and three putative metal response elements (MRE) (TGCRCNC), all located within 1100-bp upstream from the start codon. The positions of the putative HSE and MRE in the promoter region of mnp2 are compared with the corresponding sequences in the mnp1 gene promoter. A Northern blot probed with a fragment specific for the mnp2 gene suggests that the transcription of mnp2 is regulated by Mn ions.
