Identification and Characterization of a Conserved Baculoviral Structural Protein ODVP-6E/ODV-E56 from Choristoneura fumiferana Granulovirus
Bibliographic record
Abstract
A gene that encodes a homologue to baculoviral ODVP-6E/ODV-E56, a baculoviral envelope-associated viral structural protein, has been identified and sequenced on the genome of Choristoneura fumiferana granulovirus (ChfuGV). The ChfuGV odvp-6e/odv-e56 gene was located on an 11-kb BamHI subgenomic fragment using different sets of degenerated primers, which were designed using the results of the protein sequencing of a major 39 kDa structural protein that is associated with the occlusion-derived virus (ODV). The gene has a 1062 nucleotide (nt) open-reading frame (ORF) that encodes a protein with 353 amino acids with a predicted molecular mass of 38.5 kDa. The amino acid sequence data that was derived from the nucleotide sequence in ChfuGV was compared to those of other baculoviruses. ChfuGV ODVP-6E/ODV-E56, along with other baculoviral ODVP-6E/ODV-E56 proteins, all contained two putative transmembrane domains at their C-terminus. Several putative N- and O-glycosylation, N-myristoylation, and phosphorylation sites were detected in the ChfuGV ODVP-6E/ODV-E56 protein. A similar pattern was detected when a hydrophobicity-plots comparison was performed on ChfuGV ODVP-6E/ODV-E56 with other baculoviral homologue proteins. At the nucleotide level, a late promoter motif (GTAAG) was located at -14 nt upstream to the start codon of the ChfuGV odvp-6e/odv-e56 gene. A slight variant of the polyadenylation signal, AATAAT, was detected at the position +10 nt that is downstream from the termination signal. A phylogenetic tree for baculoviral ODVP-6E/ODV-E56 was constructed using a maximum parsimony analysis. The phylogenetic estimation demonstrated that ChfuGV ODVP-6E/ODV-E56 is most closely related to those of Cydia pomonella granulovirus (CpGV) and Plutella xylostella granulovirus (PxGV).

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.
