Model Card for Model ID
This model is used to predict fitness of mutant β-subunit of tryptophan synthase (TrpB) sequence. TrpB synthesizes L-tryptophan (Trp) from indole and L-serine (Ser). TrpB variant Tm9D8*, derived from the hyperthermophile Thermotoga maritima, was selected as the parent enzyme. Tm9D8* differs from wildtype TmTrpB by ten amino acid substitutions (P19G, E30G, I69V, K96L, P140L, N167D, I184F, L213P, G228S, and T292S).
