Splitting file into multiple files

I want to split text file into multiple text files based on line starting
with number(1. *) For example I want to split this text file into 2 files:

11â-Hydroxysteroid dehydrogenase 1 (11â-HSD1) catalyzes the conversion of
inactive 11-oxo glucocorticoids (endogenous cortisone,
11-dehydrocorticosterone
and synthetic prednisone) to their potent 11â-hydroxyl forms (cortisol,
corticosterone and prednisolone).
