Oligonucleotides sets used to construct the synthetic genes encoding: A,
AP-enhanced green fluorescent protein (EGFP); B, TP-EGFP; and C, VP-EGFP.
Internal repeat oligonucleotide sets were polymerized head-to-tail in the
presence of the 5′-linker sets. After ligation, the 3′ linker sets
were added. The restriction sites (underlined) were used to subclone the genes
into pUC18 (BamHI-EcoRI), then into
pUC-SStom-SP-EGFP in place of the SP gene
(XmaI-NcoI).
