Screening for novel enzymes for biocatalytic processes: accessing the metagenome as a resource of novel functional sequence space.

Published: December 2002

Historically, biotechnology has missed up to 99% of existing microbial resources by using traditional screening techniques. Strategies of directly cloning 'environmental DNA' comprising the genetic blueprints of entire microbial consortia (the so-called 'metagenome') provide molecular sequence space that along with ingenious in vitro evolution technologies will act synergistically to bring a maximum of available sequence-space into biocatalytic application.

Simultaneous localization and mapping (SLAM) techniques can be used to navigate the visually impaired, but the development of robust SLAM solutions for crowded spaces is limited by the lack of realistic datasets. To address this, we introduce InCrowd-VI, a novel visual-inertial dataset specifically designed for human navigation in indoor pedestrian-rich environments. Recorded using Meta Aria Project glasses, it captures realistic scenarios without environmental control.

Autonomous technologies have revolutionized transportation, military operations, and space exploration, necessitating precise localization in environments where traditional GPS-based systems are unreliable or unavailable. While widespread for outdoor localization, GPS systems face limitations in obstructed environments such as dense urban areas, forests, and indoor spaces. Moreover, GPS reliance introduces vulnerabilities to signal disruptions, which can lead to significant operational failures.

Accurate protein secondary structure prediction (PSSP) plays a crucial role in biopharmaceutics and disease diagnosis. Current prediction methods are mainly based on multiple sequence alignment (MSA) encoding and collaborative operations of diverse networks. However, existing encoding approaches lead to poor feature space utilization, and encoding quality decreases with fewer homologous proteins.

Fast Proxy Centers for the Jeffreys Centroid: The Jeffreys-Fisher-Rao Center and the Gauss-Bregman Inductive Center.

The symmetric Kullback-Leibler centroid, also called the Jeffreys centroid, of a set of mutually absolutely continuous probability distributions on a measure space provides a notion of centrality which has proven useful in many tasks, including information retrieval, information fusion, and clustering. However, the Jeffreys centroid is not available in closed form for sets of categorical or multivariate normal distributions, two widely used statistical models, and thus needs to be approximated numerically in practice. In this paper, we first propose the new Jeffreys-Fisher-Rao center defined as the Fisher-Rao midpoint of the sided Kullback-Leibler centroids as a plug-in replacement of the Jeffreys centroid.

Pyranose oxidase (POx) is an FAD-dependent oxidoreductase and belongs to the glucose-methanol-choline (GMC) superfamily of oxidoreductases. As recently reported, POxs and FAD-dependent -glycoside oxidases (CGOxs) share the same sequence space, and phylogenetic analysis of actinobacterial sequences belonging to this shared sequence space showed that it can be divided into four clades. Here, we report the biochemical characterization of a POx/CGOx from sp.
