Pro-Gly mediated conformational switch of mycobacteriophage D29 holin transmembrane domain I is lipid concentration driven.
Biophysical and spectroscopic analysis of synthetic transmembrane domain I (1) of mycobacteriophage D29 holin shows a lipid concentration dependent conformational switch from an α-helix to a β-sheet structure. The reversibility of this switch, upon change in the lipid-to-peptide ratio, requires a central Pro-Gly segment, and is abolished upon mutation to Ala-Ala or (D)Pro-Gly.
متن کاملFunctional analysis of the holin-like proteins of mycobacteriophage Ms6.
The mycobacteriophage Ms6 is a temperate double-stranded DNA (dsDNA) bacteriophage which, in addition to the predicted endolysin (LysA)-holin (Gp4) lysis system, encodes three additional proteins within its lysis module: Gp1, LysB, and Gp5. Ms6 Gp4 was previously described as a class II holin-like protein. By analysis of the amino acid sequence of Gp4, an N-terminal signal-arrest-release (SAR) ...
متن کاملDimerization between the holin and holin inhibitor of phage lambda.
Holins are integral membrane proteins that control the access of phage-encoded muralytic enzymes, or endolysins, to the cell wall by the sudden formation of an uncharacterized homo-oligomeric lesion, or hole, in the membrane, at a precisely defined time. The timing of lambda-infected cell lysis depends solely on the 107 codon S gene, which encodes two proteins, S105 and S107, which are the holi...
متن کاملHolin triggering in real time.
During λ infections, the holin S105 accumulates harmlessly in the membrane until, at an allele-specific time, suddenly triggering to form irregular holes of unprecedented size (>300 nm), releasing the endolysin from the cytoplasm, resulting in lysis within seconds. Here we used a functional S105-GFP chimera and real-time deconvolution fluorescence microscopy to show that the S105-GFP fusion acc...
متن کاملThe C-terminal sequence of the lambda holin constitutes a cytoplasmic regulatory domain.
The C-terminal domains of holins are highly hydrophilic and contain clusters of consecutive basic and acidic residues, with the overall net charge predicted to be positive. The C-terminal domain of lambda S was found to be cytoplasmic, as defined by protease accessibility in spheroplasts and inverted membrane vesicles. C-terminal nonsense mutations were constructed in S and found to be lysis pr...
