FIG. 3.

Nucleotide sequence of the 862-bp Sau3AI fragment containing the ipoA gene and deduced amino acid sequence of the precursor form of ipomicin. Amino acids are indicated by their one-letter designations below the nucleotide sequence. A putative Shine-Dalgarno ribosome binding sequence is underlined. The N-terminal 15 amino acids of purified ipomicin protein, which were confirmed by protein sequencing, are in bold. The site of putative cleavage of a 35-amino-acid signal sequence, which would create the mature inhibitor protein, is indicated by an arrow.
