THI20 notes (Q08224, YOL055C)

• ThiD (N-term) + TenA (C-term) fusion; THI20/THI21/THI22 family PMID:10383756.
• HMP-P kinase (EC 2.7.4.7) isofunctional with THI21 PMID:10383756.
• HMP kinase too; Thi20 much more efficient than Thi21; HMP possibly not on de novo route PMID:15614489.
• Trifunctional incl. thiaminase II PMID:15967475
• Cytosolic [PMID:16850348, curator IDA; abstract only].
• Review: 25 ACCEPT, 1 MODIFY (thiamine metabolic process -> biosynthetic), 3 KEEP_AS_NON_CORE (thiaminase x2, thiamine catabolic process).
