An unusually high substitution rate in transplant-associated BK polyomavirus in vivo is further concentrated in HLA-C-bound viral peptides. PLoS Pathog 2018; 14:e1007368. [PMID: 30335851 PMCID: PMC6207329 DOI: 10.1371/journal.ppat.1007368] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2018] [Revised: 10/30/2018] [Accepted: 09/28/2018] [Indexed: 11/18/2022] Open
Abstract
Infection with human BK polyomavirus, a small double-stranded DNA virus, potentially results in severe complications in immunocompromised patients. Here, we describe the in vivo variability and evolution of the BK polyomavirus by deep sequencing. Our data reveal the highest genomic evolutionary rate described in double-stranded DNA viruses, i.e., 10−3–10−5 substitutions per nucleotide site per year. High mutation rates in viruses allow their escape from immune surveillance and adaptation to new hosts. By combining mutational landscapes across viral genomes with in silico prediction of viral peptides, we demonstrate the presence of significantly more coding substitutions within predicted cognate HLA-C-bound viral peptides than outside. This finding suggests a role for HLA-C in antiviral immunity, perhaps through the action of killer cell immunoglobulin-like receptors. The present study provides a comprehensive view of viral evolution and immune escape in a DNA virus. Little is known about the mechanisms of evolution and viral immune escape in double-stranded DNA (dsDNA) viruses. Here, we study the evolution of BK polyomavirus and observe the highest genomic evolutionary rate described so far for a dsDNA virus, in the range of RNA viruses, which usually evolve rapidly. Furthermore, the prediction of viral peptides to determine immune escape suggests a specific role of HLA-C in antiviral immunity. These findings are helpful for future advances in antiviral therapies and provide a step forward in our understanding of in vivo viral evolution in humans.

Abstract
The human tumor necrosis factor-α converting enzyme (TACE) has recently been raised as a new and promising therapeutic target of hepatitis and other inflammatory diseases. Here, we reported a successful application of the solved crystal structure of TACE complex with a peptide-like ligand INN for rational design of novel peptide hydroxamic acid inhibitors with high potency and selectivity to target and inhibit TACE. First, the intermolecular interactions between TACE catalytic domain and INN were characterized through an integrated bioinformatics approach, with which the key substructures of INN that dominate ligand binding were identified. Subsequently, the INN molecular structure was simplified to a chemical sketch of peptide hydroxamic acid compound, which can be regarded as a linear tripeptide capped by a N-terminal carboxybenzyl group (chemically protective group) and a C-terminal hydroxamate moiety (coordinated to the Zn(2+) at TACE active site). Based on the sketch, a virtual combinatorial library containing 180 peptide hydroxamic acids was generated, from which seven samples were identified as promising candidates by using a knowledge-based protein-peptide affinity predictor and were then tested in vitro with a standard TACE activity assay protocol. Consequently, three designed peptide hydroxamic acids, i.e. Cbz-Pro-Ile-Gln-hydroxamic acid, Cbz-Leu-Ile-Val-hydroxamic acid and Cbz-Phe-Val-Met-hydroxamic acid, exhibited moderate or high inhibitory activity against TACE, with inhibition constants Ki of 36 ± 5, 510 ± 46 and 320 ± 26 nM, respectively. We also examined the structural basis and non-bonded profile of TACE interaction with a designed peptide hydroxamic acid inhibitor, and found that the inhibitor ligand is tightly buried in the active pocket of TACE, forming a number of hydrogen bonds, hydrophobic forces and van der Waals contacts at the interaction interface, conferring both stability and specificity for TACE-inhibitor complex architecture.

Abstract
![]()
Two
factors contribute to the inefficiency associated with screening
pharmaceutical library collections as a means of identifying new drugs:
[1] the limited success of virtual screening (VS) methods in identifying
new scaffolds; [2] the limited accuracy of computational methods in
predicting off-target effects. We recently introduced a 3D shape-based
similarity algorithm of the SABRE program, which encodes a consensus
molecular shape pattern of a set of active ligands into a 4D fingerprint
descriptor. Here, we report a mathematical model for shape similarity
comparisons and ligand database filtering using this 4D fingerprint
method and benchmarked the scoring function HWK (Hamza–Wei–Korotkov),
using the 81 targets of the DEKOIS database. Subsequently, we applied
our combined 4D fingerprint and HWK scoring function
VS approach in scaffold-hopping and drug repurposing using the National
Cancer Institute (NCI) and Food and Drug Administration (FDA) databases,
and we identified new inhibitors with different scaffolds of MycP1 protease from the mycobacterial ESX-1 secretion system. Experimental
evaluation of nine compounds from the NCI database and three from
the FDA database displayed IC50 values ranging from 70
to 100 μM against MycP1 and possessed high structural
diversity, which provides departure points for further structure–activity
relationship (SAR) optimization. In addition, this study demonstrates
that the combination of our 4D fingerprint algorithm and the HWK scoring function may provide a means for identifying
repurposed drugs for the treatment of infectious diseases and may
be used in the drug-target profile strategy.
