BRCA1dependentUbligaseactivity
BRCA1 is a breast and ovarian cancer tumor suppressor protein that associates with BARD1 to form a RING/RING heterodimer. The BRCA1/BARD1 RING complex functions as an ubiquitin (Ub) ligase with activity substantially greater than individual BRCA1 or BARD1 subunits. The BRCA1 tumor suppressor forms a heterodimer with the BARD1 protein, and the resulting complex functions as an E3 ubiquitin ligase that catalyzes the sy......阅读全文

什么是水活度（Water－Activity）
水活度被定义为当前可用“自由水”的量，和水分含量没有直接的对比关系，水活度值范围在0(绝对干燥)和1（100%相对湿度）之间。当物质与环境空气发生水分交换活动会在表面形成对微生物生长的理想条件，这样会影响微生物的稳定性。水活度同时也是影响食品中化学反应的重要因素。
