The downloaded human Q9HCL2 sequence (828 residues) and selected horse A0A9L0TTC1 sequence (790 residues) share 94.2% identity among 790 paired residues. Paired coverage is 95.4% of human and 100.0% of horse.
Full alignment, hashes, parameters and reproducible script: GPAM.json and compare.py.
Pairwise similarity supports homology but does not establish reciprocal orthology, intact gene models, conservation of targeting signals or every biological claim. Current UniProt sequences are compared; identity with the original ProtNLM input sequence is unverified.
The selected horse sequence lacks human residues 370–407 internally. Named human substrate-binding positions 278, 279, 288, 293, 328 and 462 remain outside this deletion, but enzymatic competence of the exact shortened sequence is not measured.
