To sequence the genome of Penicillium chrysogenum Wisconsin54-1255 and elucidate the transcriptional regulation that underpins industrial penicillin production.
Sequenced the 32.19 Mb genome of Penicillium chrysogenum reference strain Wisconsin54-1255.
Performed DNA microarray transcriptomic comparisons between the sequenced strain and a penicillin G high-producing strain cultured with and without the side-chain precursor phenylacetic acid.
Identified increased transcription of genes responsible for microbody proteins and the synthesis of penicillin amino acid precursors, including valine, cysteine, and alpha-aminoadipic acid, in the high-producing strain.
Found that genes encoding cellular transport proteins were strongly overrepresented among transcripts upregulated during stimulated penicillin G synthesis, identifying key candidates directly controlling beta-lactam yield.
