利用超快速时间分辨光谱研究了蓝绿藻藻胆体的２ 个变藻蓝发射终端（ＡＰＢ， ＡＰＩ）单体和三聚体内的能量传递过程， 探测到ＡＰＢ和ＡＰＩ单体的两组亚基αＡＰ／βＡＰ和αＡＰＢ／βＡＰ（αＡＰ／β１８）间的能量传递时间常数分别为３０ ｐｓ和１９４ ｐｓ． ＡＰＢ和ＡＰＩ三聚体所共有的９～３２ ｐｓ 的短寿命组分来源于同一单体内能量由αＡＰ向βＡＰ的传递过程． 另２ 个短寿命组分（６８ ｐｓ和５０ ｐｓ）则可分别指认为ＡＰＢ内βＡＰ→αＡＰＢ和ＡＰＩ内αＡＰ→β１８能量传递的时间常数， 所测得的长寿命组分则是几种终端基团基态恢复的平衡时间． The energy transfer of APB and API in monomer and trimer of blue-green algae gallbladder was investigated by using ultra-fast time-resolved spectroscopy. Two subunits of APB and API monomer were detected The energy transfer time constants between αAP / βAP and αAPB / βAP (αAP / β18) were 30 ps and 194 ps, respectively. APB and API trimer common 9 ~ 32 ps short-lived components derived from the same monomer within the energy transfer from αAP to βAP process. The other two short-lived components (68 ps and 50 ps) can be respectively identified as the time constants of energy transfer between APAP and αAPB in the APB and αAP → β18 in the APB. The measured long-lived components are several terminal bases The time to balance the recovery of group base state.
