PAX proteins in silico prediction in Lissachatina fulica

Prediction of snail PAX group proteins in Lisachatina fulica was performed. For this this purpose, homologous sequences to already known PAX proteins of Cephalopoda, Gastropoda and Bivalvia molluscs were predicted. The presence of certain domains (Paired box, Homeodomain and octapeptide) in the structure of the primary predicted sequences of Lisachatina fulica proteins from the GigaDB was analyzed. Also, to confirm that the sequences found belong to the PAX family proteins, their secondary and 3D structures were predicted, and their DNA-binding capacity was compared to the control Paired box domain using molecular docking. As a result, 8 proteins of Lisachatina fulica containing PAX characteristic sequences were identified. Based on the results of domain structure search and phylogenetic analysis, the proteins were categorized into 5 subfamilies of PAX proteins, namely I, III, IV, {beta}, and Pox-Neuro. The result provides a starting point for the search for the functional role of PAX proteins in the Lisachatina fulica.

In search of visual opsin of Lissachatina fulica: in silico prediction

Here we present a complex study of possible visual opsin of L. fulica. 8 candidate sequences were chosen for visual opsin protein and only one (Afu005002) was confirmed as a possible candidate after domain search, structural (structures were stimulated with AlphaFold2) and BLAST analysis. In order to evaluate spectroscopic properties of the Afu005002 protein, we have computed excitation energy and intensity of the main absorption band using QM/MM methodology at the ADC(2) level of theory. The theoretically predicted position of the main absorption maxima shows a good agreement with available experimental data.
