Directed evolution of enzymes at the crossroads of tradition and innovation
FEBS 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.

On coincidence points of generalized contractive pair mappings in convex metric spaces [PDF]
Journal of Hyperstructures, 2015 We obtain a contractive condition for the existence of coincidence points of a pair of self-mappings defined on a nonempty subset of a complete convex metric space. Moreover, we show that weakly compatible pairs have at least a common fixed point.

GENERAL FIXED POINT THEOREMS FOR WEAKLY COMPATIBLE MAPS
Demonstratio Mathematica, 2005 Summary: The purpose of this note is to use general expansive and conditions minimal type commutativity without continuity requirements to prove some fixed point theorems. The theorems extend known results from the class of compatible continuous expansive maps to a wider class of mappings.

FEBS Open Bio, EarlyView.We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Common Fixed Point of Four Mappings Satisfying Implicit Generalized Weak Contractive Type Condition
Demonstratio Mathematica, 2014 In this paper, common fixed point for four maps using an implicit contractive condition in a complete metric space is proved. Some periodic point results for such mappings are also obtained.

Journal of Function Spaces, 2022 In this article, we aim to prove various unique fixed point results for contractive and weakly compatible mappings in the sense of neutrosophic metric spaces. Several nontrivial examples are also imparted.

Common Fixed Point Theorems for Weakly Compatible Mappings
Rocky Mountain Journal of Mathematics, 2003 Let \((X,d)\) be a metric space, \(F\), \(G: X \multimap X\) be set-valued mappings and \(I\), \(J:X\to X\) two mappings. The author gives metric conditions which imply that there exists \(x \in X\) such that \(F(x)=G(x)=\{x\}\) and \(I(x)=J(x)=x\).

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma
FEBS Open Bio, EarlyView.GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Moroccan Journal of Pure and Applied Analysis, 2019 In this paper, we prove some common coupled fixed point theorems for contractive mappings in Menger metric spaces under geometrically convergent t-norms. Also, we prove common fixed point theorems for pairs of weakly compatible mappings, which generalize
