Selected U4PF58 has 51 residues; reference Q9TYJ7 has 239 residues.

Biopython PairwiseAligner global BLOSUM62, gap open -10, extension -0.5.

Reference interval Selected interval Identical residues
189–239 1–51 51

Reference feature mapping (sequence coverage does not establish retained function):

Reference feature Interval Mapped / length Identical
Domain: Glycosyltransferase 2-like 8–176 0 / 169 0

A shared segment does not establish that a truncated product folds, is expressed, localizes, or catalyzes the full-length reaction.
