Pyridoxal 5”Phosphate-dependent Histidine Decarboxylase
Pyridoxal phosphate-dependent histidine decarboxylase from Morganella morganii AM-15 was inactivated by (a-a-fluoromethylhistidine by a pseudo firstorder reaction, with KI and kinact values of 0 . 1 mM and 32.2 min-l, respectively, and was most efficient at pH 6.5-7.0. Both L-histidine and the competitive inhibitor, L-histidine methyl ester, protected against inactivation. The apoenzyme was not...
متن کاملPLPMDB: Pyridoxal-5'-phosphate dependent enzymes mutants database
SUMMARY The searchable mutant database PLPMDB has been developed to provide rapid and simple access to relevant mutant information on pyridoxal-5'-phosphate dependent enzymes. All data have been extracted from publications and publicly available databases, then organized in a relational database to enable searching via a web-based search form. The current version of PLPMDB contains 688 mutants ...
متن کاملElectroencephalographic and seizure manifestations of pyridoxal 5'-phosphate-dependent epilepsy.
We describe the electroencephalographic and clinical seizure manifestations of pyridoxal 5'-phosphate-dependent epilepsy (PLP-DE) in two patients [diagnosis confirmed by low cerebrospinal fluid (CSF) PLP, complete resolution of previously intractable seizures with PLP supplementation, negative pyridoxine-dependent epilepsy CSF biomarkers, and/or positive disease causing pyridox(am)ine 5'-phosph...
متن کاملBinding of Pyridoxal 5'-Phosphate
1. The a and ,B subforms of aspartate aminotransferase were purified from pig heart. 2. The a subform contained 2mol of pyridoxal 5'-phosphate. The apo-(a subform) could be fully reactived by combination with 2mol of cofactor. 3. The protein fluorescence of the apo(a subform) decreased non-linearly with increase in enzyme activity and concentration of bound cofactor. 4. It is concluded that the...
متن کاملTransfer of pyridoxal 5'-phosphate from albumin-pyridoxal 5'-phosphate complex to apo-aspartate aminotransferase.
Pyridoxal 5•L-phosphate (PLP) is known to combine with bovine serum albumin to form a(1:1) complex which scarcely dissociates, even when subjected to intensive dialysis. When this complex was incubated with apo-aspartate aminotransferase (apoGOT) for an appropriate time and the preincubated mixture then submitted to the usual GOT assay, the appearance of GOT activity was obviously confirmed, in...
