    • The present invention relates to the base sequence of whole genes involved in the biosynthesis of FR-008 polyketides derived from Streptomyces sp. FR-008. This base sequence comprises genes coding for ketosynthase (KS), acyl transferase (AT), acyl carrier protein (ACP), ketoreductase (KR), dehydratase (DH) and enoyl reductase (ER) domains, and genes coding for modifier enzymes, such as ABC transporter, cytochrome P450 monooxygenase, ferredoxin, thioesterase, sugar synthetic protein, FAD-dependent monooxygenase, 4-amino-4-deoxychorismate (ADC) synthase and ADC lyase. The gene base sequence according to the present invention can be used to increase the productivity of the existing FR-008 polyketides or produce new FR-008 polyketides, through modification of its parts.

    • The invention overcomes the deficiencies of the prior art by providing a rapid approach for isolating polypeptides capable of anchoring heterologous polypeptides to a bacterial inner membrane. In the technique, libraries of candidate anchor polypeptides are expressed as fusions with a heterologous polypeptide that is capable of being detected when bound to the inner membrane. In bacteria expressing a functional anchor sequence, the heterologous polypeptide becomes bound to outer face of the inner membrane. Bacteria with the functional anchor sequence can be identified by removing the outer membrane to remove non-anchored heterologous polypeptide followed by detection of anchored heterologous polypeptide. Such bacteria may be detected in numerous ways, including use of direct fluorescence or secondary antibodies that are fluorescently labeled, allowing use of efficient techniques such as fluorescence activated cell sorting (FACS).
    • 本发明克服了现有技术的缺陷,提供了一种用于分离能够将异源多肽固定在细菌内膜上的多肽的快速方法。 在该技术中,候选锚多肽的文库表达为与异源多肽的融合,当与内膜结合时能够被检测。 在表达功能性锚定序列的细菌中,异源多肽与内膜的外表面结合。 具有功能性锚定序列的细菌可以通过除去外膜以除去非锚定的异源多肽,然后检测锚定的异源多肽来鉴定。 可以以许多方式检测这些细菌,包括使用荧光标记的直接荧光或二次抗体,允许使用有效技术,例如荧光激活细胞分选(FACS)。
