  1. 16. P-type ATPases studied by electron microscopy and two-dimensional crystallization

    Författare :Kenneth Yijing Xian; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :electron microscopy; ion transport; membrane protein; P-type ATPase; two-dimensional crystallization;

    Sammanfattning : Electron microscopy and two-dimensional crystallography have been used to study the molecular structures of the porcine renal Na+,K+-ATPase and the porcine gastric H+,K+-ATPase. In addition, morphological changes have been observed with electron cryomicroscopy from tubulovesicles in porcine gastric mucosae. LÄS MER

  3. 17. Activation of the spike proteins of alpha- and retroviruses

    Nyckelord :Alphavirus; Retrovirus; Fusion protein; electron cryomicroscopy; intermediate structure;

    Sammanfattning : Enveloped viruses like human immunodeficiency virus type 1 (HIV-1) enter cells by fusing their membrane with that of the cell plasma membrane, while others, like influenzavirus and alphavirus enter via uptake into endosomes and fusion with the endosomal membrane. For this they carry spike proteins. LÄS MER
