Definition of dhaK

• Curated sequence P76015: glycerone kinase (EC 2.7.1.29). dihydroxyacetone kinase, DhaK subunit; EC 2.7.-.-. PEP-dependent dihydroxyacetone kinase, dihydroxyacetone-binding subunit DhaK; EC 2.7.1.121. dihydroxyacetone kinase subunit K (EC 2.7.1.121). dihydroxyacetone kinase subunit K
• Curated sequence Q92EU2: PTS-dependent dihydroxyacetone kinase 2, dihydroxyacetone-binding subunit DhaK; EC 2.7.1.121
• Curated sequence Q9CIV8: PTS-dependent dihydroxyacetone kinase, dihydroxyacetone-binding subunit DhaK; EC 2.7.1.121
• Ignore hits to items matching 2.7.1.121 when looking for 'other' hits
• Ignore hits to A0A1D3TV19 when looking for 'other' hits (glycerone kinase (EC 2.7.1.29))
• Comment: most prokaryotic dihydroxyacetone kinases are heteromeric and use phosophoenolpyruvate rather than ATP as the phosphoryl donor (EC 2.7.1.121) This is a PTS-like system that relies on EI and Hpr proteins to phosphorylate the dhaM subunit The BRENDA entry does not actually seem to be characterized, not clear if it is dhaK or dhaK'

Fetched 3 sequences

Running ublast to find other characterized proteins with 40% identity and 70% coverage

Found hits to 4 other characterized sequences. (Found 7 hits including self hits.)

Removing ignored items reduces this to 3 close sequences.
