WebHere, we report a protein engineering-based enhancement of the crystallizability of a penicillin G acylase from Bacillus sp. FJAT-27231 (FJAT-PGA), recombinantly secreted with Priestia megaterium. Starting with wild-type FJAT-PGA, the first improvements were achieved by surface entropy reduction, enabling new crystal contacts. Based on … Crystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid
