The Major Cell Envelope Protein ofMicrococcus radiodurans(R1)

Getting across the cell envelope: mycobacterial protein secretion.

Protein secretion is an essential determinant of mycobacterial virulence. Mycobacterium tuberculosis has a unique cell envelope consisting of two lipid bilayers, which requires dedicated protein secretion pathways. The conserved general Sec and Tat translocation systems are responsible for protein transport across the inner membrane and are both essential. Additionally, the accessory Sec pathwa...

Cell Envelope Structure and Functions in Gram-negative Bacteria

The bacterial cell envelope.

The major 67 000 molecular weight protein of the clam oocyte nuclear envelope is lamin-like.

Nuclear envelopes of somatic cells have at least two different major proteins in the 60-70(X 10(3] molecular weight range (lamins A(C) and B) that seem to be involved in chromatin attachment. In contrast, nuclear envelopes from clam germinal vesicles have only a single major protein of the same size class (approximately 67 X 10(3) Mr) and have no chromatin attached to them. The data presented i...

Lipase activities of p37, the major envelope protein of vaccinia virus.

p37, the major protein of the extracellular enveloped form of vaccinia virus, is involved in the biogenesis of the viral double membrane and in egress of virus from the cell. p37 was expressed as a glutathione S-transferase fusion protein and was purified to homogeneity by silver staining using glutathione-agarose, Sephacryl S-200, and DEAE-cellulose chromatography. Incubation of p37 with phosp...
