Function

[YBDL_ECOLI] Shows aminotransferase activity with methionine and histidine as substrates, and to a lesser extent also with phenylalanine.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

The ybdL gene of Escherichia coli codes for a protein of unknown function. Sequence analysis showed moderate homology to several vitamin B(6) dependent enzymes, suggesting that it may bind pyridoxal-5'-phosphate. The structure analysis of YbdL to 2.35 A resolution by protein crystallography verifies that it is a PLP dependent enzyme of fold type I, the typical aspartate aminotransferase fold. The active site contains a bound pyridoxal-5'-phosphate, covalently attached to the conserved active site lysine residue Lys236. The pattern of conserved amino acids in the putative substrate binding pocket of the enzyme reveals that it is most closely related to a hyperthermophilic aromatic residue aminotransferase from the archeon Pyrococcus horikoshii. Activity tests with 10 amino acids as amino-donors reveal, however, a preference for Met, followed by His and Phe, results which can be rationalized by modelization studies.
