The lysin motif (LysM) containing proteins can bind chitin and are ubiquitous in various organisms including fungi. In plant pathogenic fungi, a few LysM have been characterized as effectors to suppress chitin-induced immunity hosts therefore contribute fungal virulence. effector mechanism is still questioned fungus-animal interactions. this study, we found that also present animal fungi evolved divergently. genome of the insect pathogen Beauveria bassiana encodes 12 proteins, genes were...

Biological methylation is a fundamental enzymatic reaction for variety of substrates in multiple cellular processes. Mammalian N6amt1 was thought to be homologue bacterial N(6)-adenine DNA methyltransferases, but its substrate specificity and physiological importance remain elusive. Here, we demonstrate that functions as protein methyltransferase the translation termination factor eRF1 mammalian cells both vitro vivo. Mass spectrometry analysis indicated about 70% endogenous methylated at...

Although the cerebral cortex is thought to be composed of functionally distinct areas, actual parcellation area and assignment function are still highly controversial. An example much-studied lateral intraparietal (LIP). Despite general agreement that LIP plays an important role in visual-oculomotor transformation, it remains unclear whether primary sensory- or motor-related (the attention-intention debate). has been considered as a unitary area, its dorsal (LIPd) ventral (LIPv) parts differ...

Semi-flexible polymers, such as actin filaments, can deform the shape of membrane when confined in a vesicle, playing an important role biological processes. Here, we use dynamic Monte Carlo simulations to study active polymer chain vesicle. For flexible chains, is governed by competition between bending rigidity and activity. Stiff unaffected small forces, but moderate forces cause alternate stretched disordered configurations, increasing asphericity both semi-flexible their stiffness...

The adsorption of polymers onto fluid membranes is a problem fundamental interest in biology and soft materials, part because the flexibility can lead to nontrivial coupling between polymer membrane configurations.
