Transformations of edge-colourings of cubic graphs

open access: yesDiscrete Mathematics, 1975
AbstractIn this paper we shall study and describe all possible forms of the so-called change-graph which is the subgraph of a cubic graph G containing all the edges (and only the edges) having different colours in two different edge-colourings of G.

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

open access: yesFEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

JUST CHROMATIC EXCELLENCE IN FUZZY GRAPHS

open access: yesJournal of New Theory, 2017
Abstaract−Let G be a simple fuzzy graph. A family Γf= {γ, γ2, . . . , γk} of fuzzy sets on a set V is called k-fuzzy colouring of V = (V, σ, µ) if i)∪Γf= σ, ii) γi∩ γj= ∅, iii)for every strong edge (x, y)(i.e., µ(xy) > 0) of G min{γi(x), γi(y)} = 0 ...

Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

open access: yesFEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Recent progress on edge-colouring graphs

open access: yesDiscrete Mathematics, 1987
Suppose G is a multigraph without loops. Let \(\chi\) '(G) and \(\Delta\) (G) denote respectively the chromatic index and the maximum degree of G. If \(\chi '(G)=\Delta (G)\), then G is said to be Class 1, and otherwise G is Class 2. A graph G is said to be overfull, if \(| E(G)| >\Delta (G)\lfloor | V(G)| \rfloor.\) This paper summarizes some of the ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
