MFIB
收藏资源简介:
MFIB database collects and classifies protein complexes, wherein all constituent protein chains would be unstable/disordered in isolation but fold into a well-defined 3D complex structure upon binding.we collected and annotated hundreds of new protein complexes fulfilling the criteria of MSF, leading to an almost six-fold increase in the size of the database. Many novel features have also been introduced, such as clustering of the complexes based on structural similarity and domain types, assigning different evidence levels to each entry and adding the evidence coverage label that allowed us to include complexes of multi(sub)domain monomers with partial MSF.
MFIB数据库用于收集并分类蛋白质复合物,其收录的所有组成蛋白质链在孤立状态下均不稳定或易呈现无序构象,但在相互结合后可折叠为结构明确的三维复合物结构。本次研究中,我们收集并注释了数百个符合MSF标准的新型蛋白质复合物,使该数据库的规模扩大了近六倍。此外还新增了多项创新性功能:包括基于结构相似性与结构域类型对复合物进行聚类、为每条数据条目分配不同的证据等级,以及添加证据覆盖标签,借此得以纳入包含部分MSF结构的多(亚)结构域单体所形成的复合物。
