This insertion presumably causes severe destabilization of the fold of the protein, leading to an inactive enzyme that is very quickly degraded. The cryptic GudB serves as a buffer that may compensate for mutations in the rocG gene and that can also be decryptified for the utilization of glutamate as a single carbon [...] | 0.956 |
