最简单的一类与寄生虫相关的细胞器(MRO)是有丝分裂体,这是一种存在于一些厌氧原生动物寄生虫中的细胞器,如溶组织内阿米巴,贾第鞭毛虫和隐孢子虫。E.溶组织菌引起人类阿米巴病,被认为是世界上重要但被忽视的热带感染之一。E.溶组织菌线粒体围绕明显缺乏大多数已知的线粒体组分和在其他生物体中表现出的功能。硫酸盐活化酶的鉴定(AS、IPP和APSK)和许多谱系特异性蛋白,如外膜β桶蛋白(MBOMP30)和与各种细胞器蛋白结合的含跨膜结构域的蛋白(ETMP1、ETMP30、EHI_170120和EHI_099350)显示了与厌氧原生动物的其他MRO相比,该细胞器的显著差异。在这里,我们总结了关于E.从他们的发现到目前对其作用和相互作用的理解。我们还包括目前的进展和未来的生物学,生物化学和进化的丝裂体的E。溶组织剂
The simplest class of mitochondrion‐related organelles (MROs) is the mitosome, an organelle present in a few anaerobic protozoan parasites such as Entamoeba histolytica, Giardia intestinalis, and Cryptosporidium parvum. E. histolytica causes amoebiasis in humans, deemed as one of the important, yet neglected tropical infections in the world. Much of the enigma of the E. histolytica mitosome circles around the obvious lack of a majority of known mitochondrial components and functions exhibited in other organisms. The identification of enzymes responsible for sulfate activation (AS, IPP, and APSK) and a number of lineage‐specific proteins such as the outer membrane beta‐barrel protein (MBOMP30), and transmembrane domain‐containing proteins that bind to various organellar proteins (ETMP1, ETMP30, EHI_170120, and EHI_099350) showcased the remarkable divergence of this organelle compared to the other MROs of anaerobic protozoa. Here, we summarize the findings regarding the biology of the mitosomes in E. histolytica, from their discovery up to the present understanding of its roles and interactions. We also include current advances and future perspectives on the biology, biochemistry, and evolution of the mitosomes of E. histolytica.
