Holin function
Did you know?
Holins are a diverse group of small proteins produced by dsDNA bacteriophages in order to trigger and control the degradation of the host's cell wall at the end of the lytic cycle. Holins form pores in the host's cell membrane, allowing lysins to reach and degrade peptidoglycan, a component of bacterial cell … Se mer Structure According to their structure there are three main classes of holins. Class I holins Class I holins have three transmembrane domains (TMDs) … Se mer • Lysin • Lytic cycle Se mer • Reddy, Bhaskara L.; Saier Jr, Milton H. (2013).

Nettet25. sep. 2008 · Here, we show that holin-independent cell lysis brought about by SAR endolysins is blocked by millimolar concentrations of divalent cations and that this blockage is relieved by co-expression of a non-cognate Rz/Rz1 lysis gene pair. This would appear to rule out any direct role for holin proteins in the function of the Rz–Rz1 … NettetThe primary regulation of holin function, however, appears to be intrinsic to the holin structure itself, since a missense allele of the S holin gene of phage λ has been found which abolishes the normal delay that allows the vegetative phase to generate a useful number of progeny.
