The role includes refining custom tools and algorithms to facilitate identification of therapeutic leads from OmniAb immune repertoires and applying cutting edge computational biology approaches to all stages of antibody discovery, from antigen…

What is abrin? In certain parts of Asia and Australia, grows a flowering plant of the bean family Fabaceae, known as Abrus precatorius, also more commonly as jequirity bean or rosary pea [1]. It’s a delicate, perennial climber but extremely invasive and classified as a weed in several countries. However, what…

Peptide conjugation to trastuzumab A 23 amino acid peptide, acetyl-(Lys[Azide]) RRRGSGPDCAYHKGELVWCTFH-NH2, was chemically synthesized and modified with a succinimidyl glutarate linker at Lys14 (the numbering starts with Lys[Azide]) (Fig. 1A). To allow payload conjugation and increase the solubility of the conjugates, the N-terminus of the peptide was extended based on a…

Protein production Soluble spike constructs were purified from supernatants of transiently or stably transfected CHO cells; a summary of all constructs tested in this study is provided in Supplementary Table 1. Purified proteins separated by SDS-PAGE and stained with Coomassie Blue are shown in Supplementary Fig. 1. All variants show high…

Search RCSB with a list of protein names? 1 Hi, I have a text file with 1000 different proteins (EDIT: proteins, not PDB-IDs), and I would like to gather all the structural information related to them from RCSB. I have never done any high-throughput work with RCSB, and the list…

GROMACS version: 2021.4-Ubuntu-2021.4-2GROMACS modification: NoHere post your questionI am trying to run pdb2gmx for a pdb with a modified residue with Amber96 forcefield and TIP3P water. I have modified aminoacids.rtp and aminoacids.hdb files to include the modified residue (chromophore in 1bfp). When I am running, the following error comes: Fatal…

Phylogenetic analysis Protein sequences of spike proteins were downloaded from the NCBI virus database for all the known sarbecoviruses (June 2020). A multiple sequence alignment was generated using MUSCLE36. The resulting multiple sequence alignment was pruned to the RBD region, filtered at 95% sequence identity and used as input for…

Help writing code for a question on my homework 1 Hello! I am taking my first programming class and I am struggling with some questions on my biopython homework. I can’t figure out how to work with the files and how to get the sequence from the file in order…

Construction of integrated PCEG and PCEP To the best of our knowledge, the present study is the first to develop a comprehensive catalog of plastic-contaminated soils using an integrated bioinformatic workflow. Five datasets were used to produce 53,300,583 unique genes and proteins. Quality control of reads, trimming, assembly, and binning…
