| Type: | Domain | Name: | Phosphoserine phosphatase, domain 2 |
| Description: | Phosphoserine phosphatases (PSP) are members of a large group of enzymes responsible for phosphoester hydrolysis using a phosphoaspartate-enzyme intermediate. Reversible protein phosphorylation is essential for regulation of basic cell function such as DNA replication, gene transcription and protein translation. The phosphoserine phosphatases are related to the P-type ATPases and haloacid dehydrogenases, with which they share 3 conserved sequence motifs [].The crystal structures of PSP, PSP in complex with its substrate and in complex with a transition state analogue have been solved, giving extensive insight into the catalytic mechanism of phosphoserine phosphatases []. This entry represents the second domain, which is predominantly alpha helical. | Short Name: | Pser_Pase_dom_2 |
