The purpose of this work was to identify the function of bacterial homologues of fructosamine 3-kinase (FN3K), a mammalian enzyme responsible for the removal of fructosamines from proteins. FN3K homologues were identified in approximately 200 (i.e. approximately 27%) of the sequenced bacterial genomes. In 11 of these genomes, from phylogenetically distant bacteria, the FN3K homologue was immediately preceded by a low-molecular-weight protein-tyrosine-phosphatase (LMW-PTP) homologue, which is therefore probably functionally related to the FN3K homologue. Five bacterial FN3K homologues (from Escherichia coli, Enterococcus faecium, Lactobacillus plantarum, Staphylococcus aureus and Thermus thermophilus) were overexpressed in E. coli, purified and their kinetic properties investigated. Four were ribulosamine/erythrulosamine 3-kinases acting best on free lysine and cadaverine derivatives, but not on ribulosamines bound to the alpha amino group of amino acids. They also phosphorylated protein-bound ribulosamines or erythrulosamines, but not protein-bound fructosamines, therefore having properties similar to those of mammalian FN3K-related protein. The E. coli FN3K homologue (YniA) was inactive on all tested substrates. The LMW-PTP of T. thermophilus, which forms an operon with an FN3K homologue, and an LMW-PTP of S. aureus (PtpA) were overexpressed in E. coli, purified and shown to dephosphorylate not only protein tyrosine phosphates, but protein ribulosamine 5-phosphates as well as free ribuloselysine 5-phosphate and erythruloselysine 4-phosphate. These LMW-PTPs were devoid of ribulosamine 3-phosphatase activity. It is concluded that most bacterial FN3K homologues are ribulosamine/erythrulosamine 3-kinases. They may serve, in conjunction with a phosphatase, to deglycate products of glycation formed from ribose 5-phosphate or erythrose 4-phosphate. << Less
