What it is Filled

An enzyme of class EC 2.7 that transfers a phosphorus-containing group from a donor, usually ATP, to an acceptor, including kinases that transfer phosphate groups, such as gluconate kinase and dephospho-CoA kinase, and nucleotidyltransferases that transfer nucleotide groups, such as FMN adenylyltransferase and phosphatidate cytidylyltransferase, along with specialised families such as the KptA/Tpt1 tRNA phosphotransferases; phosphotransferases are central to signalling and metabolism.

Why it exists Filled

Let an agent explain phosphotransferases and their subclasses, relay mechanisms and biological roles from biochemistry sources, describe the enzymes the registry aliases name, and distinguish phosphotransferases from phosphatases, phosphorylases and the bacterial phosphotransferase sugar transport system.

Distinguishing features Filled

  • Group transfer
  • Kinases and nucleotidyltransferases
  • ATP donors
  • Central to metabolism

What robots and AI may and may not do Filled

Must not

  • Treat specific enzymes in the aliases as synonyms of the whole class.
  • Give medical advice based on enzyme functions for a specific person.
  • Invent EC numbers or enzyme activities.

Only with a human decision

  • Changing curated enzyme classification records.

May

  • Explain phosphotransferases of EC 2.7 and their subclasses, citing enzyme nomenclature sources.
  • Distinguish them from phosphatases and from the bacterial PTS.

Moral aspects Filled

  • Errors in enzyme classification propagate through databases and research.
  • Kinase drugs are medical topics where individual advice needs a clinician.

Who is affected

  • Researchers and students
  • Curators of biological databases

Owners Filled

Steward

Nobody owns the class; the international enzyme nomenclature committee maintains its classification.

Master systems

  • Enzyme nomenclature lists of the international biochemistry union

Links to other meta-models Filled

parent

  • Q407355 - registry parent class

related

  • transferase - in registry terms
  • kinase - as a major subclass
  • phosphatase - which removes phosphate
  • adenosine triphosphate - as a common donor

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.phosphotransferase
  • Wikidata: Q3381520 (https://www.wikidata.org/wiki/Q3381520)
  • EC: 2.7 transferring phosphorus-containing groups
  • MeSH: D010770 Phosphotransferases

Direct properties required Filled

  • EC class: EC 2.7 note
  • human protein kinases: about 500 count - kinome
  • common donor: ATP note

Recognition required Filled

  • Enzymes transferring phosphorus-containing groups
  • Kinases such as gluconate kinase and dephospho-CoA kinase; nucleotidyltransferases such as FMN adenylyltransferase and phosphatidate cytidylyltransferase; KptA/Tpt1
  • Phosphatases remove phosphate; phosphorylases add inorganic phosphate; the PTS is a transport system
  • Not a visible object; proteins.

Capabilities and actions required Filled

  • explain the class
  • relay mechanisms and roles
  • describe named enzymes
  • distinguish related enzymes

Hazards and failure modes required Filled

  • Confusing phosphotransferases with phosphatases
  • Registry aliases mixing subclasses and specific enzymes
  • Confusing with the bacterial PTS

Standards and interfaces required Filled

  • IUBMB enzyme nomenclature

Context of use required Filled

  • Not applicable; an enzyme class.
  • protein kinases
  • metabolic kinases such as gluconate and dephospho-CoA kinase
  • nucleotidyltransferases such as FMN adenylyltransferase
  • CDP-diacylglycerol synthases such as phosphatidate cytidylyltransferase
  • RNA phosphotransferases such as KptA/Tpt1

Sources Filled

  1. Wikidata item Q3381520: phosphotransferase - identity and sense of the item
  2. Wikipedia: Phosphotransferase - general description of the item

Open questions

  • Should kinase and nucleotidyltransferase be separate primary entries?
  • How should biochemistry sources be linked?
  • The registry entry has merged aliases naming specific enzymes; should they be split off?
