Simplified ancestral enzyme makes ATP without amino acid needed for its usual reaction
Proteins perform essential functions in living organisms, from catalyzing biochemical reactions to supporting cellular energy metabolism. Their functions depend on their amino acid composition and three-dimensional structures. However, early proteins may have evolved when fewer amino acid types were...

Proteins perform essential functions in living organisms, from catalyzing biochemical reactions to supporting cellular energy metabolism. Their functions depend on their amino acid composition and three-dimensional structures. However, early proteins may have evolved when fewer amino acid types were available than those used by most modern proteins.
