Webb18 okt. 2024 · Moreover, the reaction intermediate pyridoxamine-5'-phosphate (PMP) was released more slowly into the bulk, indicating that the mutation also enhances their PMP binding capacity. The crystal structure of PfTA, elucidated in this work, revealed a tetrameric arrangement with the PLP binding sites near the subunit interface. WebbBased on the observation that the addition of l-cysteine can reproduce the 350-nm species, we tentatively assign this feature to a substrate-PLP intermediate that is captured by the H123A mutation. This 350-nm species is stable as it is still present 150 min after l -cysteine addition ( Fig. 3 B ), which is in agreement with the results presented in Fig. 2 .
