Essential Twisted Surfaces in Alternating Link Complements
Checkerboard surfaces in alternating link complements are used frequently to determine information about the link. However, when many crossings are added to a single twist region of a link diagram, the geometry of the link complement stabilizes (approaches a geometric limit), but a corresponding checkerboard surface increases in complexity with crossing number. In this paper, we generalize chec...
متن کاملAn essential connection: link between Hsp70's domains at last.
Communication between the ATPase and substrate binding domains of Hsp70 is critical for regulated interaction between this molecular chaperone and its client proteins. In this issue of Molecular Cell, Jiang et al. (2005) report the structure of an intact Hsp70, revealing critical interactions between the two domains.
متن کاملModelling Frameworks: The Essential Link Between Models and Methodologies
The representation of abstractions through models is an over-arching theme in system development methodologies. In order to express all the subtleties of complex systems, methodologies suggest the use of several models, with each representing some aspects of the universe of discourse. Unfortunately, there is no universal agreement about which aspects of the existing and/or the new information s...
متن کاملBiodiversity and human well-being: an essential link for sustainable development
As society strives to transition towards more sustainable development pathways, it is important to properly conceptualize the link between biodiversity (i.e. genes, traits, species and other dimensions) and human well-being (HWB; i.e. health, wealth, security and other dimensions). Here, we explore how published conceptual frameworks consider the extent to which the biodiversity-HWB links are b...
متن کاملStructure of mycobacterial maltokinase, the missing link in the essential GlgE-pathway
A novel four-step pathway identified recently in mycobacteria channels trehalose to glycogen synthesis and is also likely involved in the biosynthesis of two other crucial polymers: intracellular methylglucose lipopolysaccharides and exposed capsular glucan. The structures of three of the intervening enzymes - GlgB, GlgE, and TreS - were recently reported, providing the first templates for rati...
