Structural and Biochemical Investigation of Heptad Repeat Derived Peptides of Human SARS Corona Virus (hSARS-CoV) Spike Protein+
Bibliographic record
Abstract
hSARS-CoV is the causative agent for SARS infection. Its spike glycoprotein (S) is processed by host furin enzyme to produce S1 and S2 fragments, the latter being crucial for fusion with the host membrane. This takes place via formation of a coiled coil 6-helix bundle involving N and C-terminal heptad repeat domains (HR-N and HR-C) of S2. Several fluorescent and non-fluorescent peptides from these domains were synthesized to examine their interactions by circular dichroism, thermal denaturation, native-page, mass spectrometry and fluorescence spectroscopy studies. Data revealed that HR-C domains (1153-1189), (1153-1172) and (1164-1184) all exhibit potent binding interactions with HR-N(892-931) domain. These peptides may find useful therapeutic applications in SARS intervention.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
