title: Constraints Aware Plasticity Ceiling Mapping of the MERS-CoV Spike Glycoprotein: DPP4 Interface Remodeling, Cleavage Site Optimization, and Immune Escape Signatures

description: This dataset characterizes evolutionary boundaries of the Middle East respiratory syndrome coronavirus (MERS-CoV) spike glycoprotein through domain-resolved constraint analysis and boundary-state enumeration across three functional regions:

(1) the receptor-binding domain interface with host receptor DPP4, where codon permissiveness scores identify contact residues with elevated evolutionary plasticity permitting human-adaptive substitutions;

(2) the S1/S2 proteolytic cleavage motif, where boundary analysis reveals theoretical capacity for furin optimization toward polybasic configurations;

(3) non-contact surface residues supporting antigenic variation without compromising receptor engagement.

Domain architecture mapping confirms lethal constraints in the structural core and fusion machinery, which remain invariant across all boundary instantiations. The dataset includes nucleotide and protein FASTA files for three boundary states (receptor affinity enhancement, immune escape, cleavage optimization), codon permissiveness annotations derived from 1,746 global isolates, and domain-resolved constraint maps.

Complete residue-level boundary specifications are provided in the restricted file impacted_residues.txt accompanying this deposition. These resources enable genomic surveillance pipelines to detect natural isolates approaching theoretically permissible fitness boundaries at receptor engagement and proteolytic activation sites.
description: DURC Compliance Statement

This dataset contains computationally derived boundary sequences representing theoretical upper limits of MERS-CoV spike glycoprotein evolution under purifying selection constraints. All instantiations were generated in silico using codon permissiveness scoring from 1,746 global isolates and respect lethal structural constraints in the RBD core and fusion machinery. No experimental protocols for viral reconstruction, reverse genetics, phenotypic enhancement, or gain-of-function research are provided, implied, or endorsed.

The dataset serves exclusively defensive purposes:Enabling genomic surveillance pipelines to detect natural isolates approaching theoretically permissible fitness boundaries at the DPP4 interface and proteolytic activation sites. 

Supporting anticipatory risk assessment for pandemic preparedness agenciesInforming early-warning rule development for public health monitoring systems

All boundary sequences represent states already permitted by natural purifying selection, not novel enhancements beyond existing evolutionary capacity. 

Access to residue-level specifications is restricted to qualified researchers who affirm use solely for defensive surveillance and biosecurity assessment under institutional DURC review frameworks.

This work complies with the U.S. Government Policy for Institutional Oversight of Life Sciences Dual Use Research of Concern (2012/2017) and WHO Guidance on Responsible Life Sciences Research.

description: Patient postcode linked measures are available for patients in English practices that have consented to participate in the linkage scheme. The latest available patient postcode of residence is mapped to an LSOA boundary. The LSOA of residence then allows linkage to several measures of area level deprivation and a rural-urban classification. These measures can be used as a proxy for socio-demographic and socio-economic data which are generally poorly recorded in the primary care data given they do not directly relate to a patient's care.
