Abstract: Provided herein are systems and methods for nucleotide incorporation reactions. The systems comprise polymerases having altered nucleotide incorporation kinetics and are linked to an energy transfer donor moiety, and nucleotide molecules linked with at least one energy transfer acceptor moiety. The donor and acceptor moieties undergo energy transfer when the polymerase and nucleotide are proximal to each other during nucleotide binding and/or nucleotide incorporation. As the donor and acceptor moieties undergo energy transfer, they generate an energy transfer signal which can be associated with nucleotide binding or incorporation. Detecting a time sequence of the generated signals, or the change in the signals, can be used to determine the order of the incorporated nucleotides, and can therefore be used to deduce the sequence of the target molecule.

Abstract translation: 本文提供了用于核苷酸掺入反应的系统和方法。 该系统包含具有改变的核苷酸掺入动力学并且与能量转移供体部分连接的聚合酶，以及与至少一个能量转移受体部分连接的核苷酸分子。 当核苷酸结合和/或核苷酸掺入期间聚合酶和核苷酸彼此接近时，供体和受体部分进行能量转移。 当供体和受体部分进行能量转移时，它们产生可与核苷酸结合或掺入相关联的能量转移信号。 检测所产生的信号的时间序列或信号的变化可用于确定掺入的核苷酸的顺序，因此可用于推导靶分子的序列。
