Domain	Start	End	Length (AA)	Confidence
N-terminal	1	317	317	0,9969
Central domain	318	317	1	0,4450
C-terminal	318	319	1	0,5564

Note: Constraints were applied during segmentation.
C-terminal too short, adjusted boundary|CONSTRAINT VIOLATION: Final C-terminal (1 AA) is still below minimum (10 AA). Sequence may be too short.
