Characterization of Sphingomonas sp. KT-1 PahZ1 Interface Mutant Domain via Crystallization and QM/MM

Poly Aspartic Acids (PAAs) are water soluble plastics that have a variety of uses, mainly as a super-swelling material in feminine hygiene products.  -River water bacteria Sphingomonas sp. KT-1 was discovered to  degrade PAA to Oligoaspartic Acid (OAA) through specific cleavage of the β-amide linkages. The project goal is to characterize the 2 proteins that are responsible for PAA breakdown, and their monomeric forms to understand how to link the 2 proteins together to form a functioning chimera protein that can break down PAA to monomeric aspartic acid for protein engineering to catalyze the biodegradation of other xenobiotics.
