Ofatumumab Monoclonal Antibody Affinity Maturation Through in silico Modeling

PMCID: 5889503
DOI: 10.22034/ibj.22.3.180

[…] e, specifically the values for the active sites were much higher. This result suggests that pockets contribute to the prediction of binding sites, and active sites from protein structures. GHECOM and CASTp results are shown in and . […]


An allosteric inhibitor of Mycobacterium tuberculosis ArgJ: Implications to a novel combinatorial therapy

PMCID: 5887547
PMID: 29483133
DOI: 10.15252/emmm.201708038

[…] ed our quest to discover a small molecule inhibitor of MtArgJ by investigating the protein surface. MtArgJ structure (PDB ID: 3IT6) was probed for surface cavity predictions (by MetaPocket server and CastP analysis) and a well‐defined pocket of area 2,019.7 Å2 and volume 3,104.8 Å3 located in‐between the two active sites was discovered (Fig A). This pocket comprises of 48% hydrophobic amino acid r […]


Crystal structure of IspF from Bacillus subtilis and absence of protein complex assembly amongst IspD/IspE/IspF enzymes in the MEP pathway

[…] The cavity analysis was performed using CASTp server [], surface calculations were performed by ArealMol from CCP4 programs suite []. […]


Structural and Biochemical Characterization of BdsA from Bacillus subtilis WU S2B, a Key Enzyme in the “4S” Desulfurization Pathway

Front Microbiol
PMCID: 5819316
PMID: 29497411
DOI: 10.3389/fmicb.2018.00231

[…] y component of the active pocket, which, along with IS1, IS2, and IS3, controls the size of the pocket. The volume of the active pocket of BdsA, and those of homologous proteins, are calculated using CASTp server (). The volume of the BdsA activity pocket is 5134.9 Å3. Nitrilotriacetate monooxygenase catalyzes the degradation of the nitrilotriacetate substrate, with the active pocket volume of 528 […]


The structure of FIV reverse transcriptase and its implications for non nucleoside inhibitor resistance

PLoS Pathog
PMCID: 5798851
PMID: 29364950
DOI: 10.1371/journal.ppat.1006849
call_split See protocol

[…] ted using ESPript []. PyMOL Molecular Graphics System (Schrödinger, LLC) was used for preparing structural figures and for structural superposition. Comparative pocket volumes were analyzed using the CASTp server [] using HIV-1 RT bound to NVP without nucleic acid (PDB code: 5HBM) or bound to NVP with nucleic acid (PDB code: 4PUO). Both HIV-1 RT structures show comparable volumes validating the us […]


Alanine mutation of the catalytic sites of Pantothenate Synthetase causes distinct conformational changes in the ATP binding region

Sci Rep
