Effective structure of a leader open reading frame for enhancing the expression of GC-rich genes.

Abstract excerpt

To overexpress broad kinds of GC-rich genes in Escherichia coli, we examined how the structures of leader open reading frames (leader ORFs) affect the expression of GC-rich genes, such as polA, trpA, and trpB, from Thermus thermophilus. When a leader ORF overlapped with the polA-initiation codon by 1 bp in the TGATG motif, gene expression increased by more than 3-fold compared to when a leader ORF was several-bp...
