Phylogenetic and AlphaFold predicted structure analyses provide insights for A1 aspartic protease family classification in Arabidopsis

Introduction Proteases regulate various biological processes including protein synthesis and maturation, activity modification, degradation and turnover. Depending on their catalytic mechanisms, these proteases are primarily classified into cysteine, metallo-, serine, threonine and aspartic protease family (Beers et al., 2004). The latter protease family is known as acid protease family because they…

Phenotypic characterization and analysis of complete genomes of two distinct strains of the proposed species “L. swaminathanii”

Since 2010, there have been multiple new species added to the Listeria genus, many originally isolated from natural environments16. This paper describes the genotypic and phenotypic characterization of two new Listeria isolates obtained from soil samples collected in the Great Smoky Mountains National Park along the North Carolina-Tennessee border17. Evaluation…

Introduction to the BLAST Suite and BLASTN | Michael Agostino

Butterfly eyespots evolved via cooption of an ancestral gene-regulatory network that also patterns antennae, legs, and wings

Although the hypothesis of gene-regulatory network (GRN) cooption is a plausible model to explain the origin of morphological novelties (1), there has been limited empirical evidence to show that this mechanism led to the origin of any novel trait. Several hypotheses have been proposed for the origin of butterfly eyespots,…

taxonomy – Assign multiple taxids to a sequence when constructing a local BLAST database

I recently had a script fail due to poor handling of BLAST output.

Fixing the script to handle this should be fairly straightforward. But the…
