Detection of an interaction between the HN and F proteins in Newcastle disease virus-infected cells.
For many paramyxoviruses, including Newcastle disease virus (NDV), syncytium formation requires the expression of both surface glycoproteins (HN and F) in the same cell, and evidence suggests that fusion involves a specific interaction between the HN and F proteins. Because a potential interaction in paramyxovirus-infected cells has never been demonstrated, such as interaction was explored by u...
متن کاملTracking F plasmid TraI relaxase processing reactions provides insight into F plasmid transfer
Early in F plasmid conjugative transfer, the F relaxase, TraI, cleaves one plasmid strand at a site within the origin of transfer called nic. The reaction covalently links TraI Tyr16 to the 5'-ssDNA phosphate. Ultimately, TraI reverses the cleavage reaction to circularize the plasmid strand. The joining reaction requires a ssDNA 3'-hydroxyl; a second cleavage reaction at nic, regenerated by ext...
متن کاملAlternative mechanisms of interaction between homotypic and heterotypic parainfluenza virus HN and F proteins.
Cell fusion by human parainfluenza virus (HPIV) type 2 or type 3 requires the coexpression of both the fusion (F) and haemagglutinin-neuraminidase (HN) glycoproteins from the same virus type, indicating that promotion of fusion requires a type-specific interaction between F and HN. In this report we have further investigated the interaction of the ectodomains of the F and HN glycoproteins from ...
متن کاملOn the gap between ess(f) and cnf_size(f)
Given a Boolean function f , the quantity ess(f) denotes the largest set of assignments that falsify f , no two of which falsify a common implicate of f . Although ess(f) is clearly a lower bound on cnf size(f) (the minimum number of clauses in a CNF formula for f), C̆epek et al. showed it is not, in general, a tight lower bound [1]. They gave examples of functions f for which there is a small g...
متن کاملF-box proteins everywhere.
The ubiquitin proteasome system is a key regulator of many biological processes in all eukaryotes. This mechanism employs several types of enzymes, the most important of which are the ubiquitin E3 ligases that catalyse the attachment of polyubiquitin chains to target proteins for their subsequent degradation by the 26S proteasome. Among the E3 families, the SCF is the best understood; it consis...
