Source-derived summary

In enzymology, a threonine racemase (EC 5.1.1.6) is an enzyme that catalyzes the chemical reaction

L-threonine

⇌

{\displaystyle \rightleftharpoons }

D-threonine

Hence, this enzyme has one substrate, L-threonine, and one product, D-threonine.

This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on amino acids and derivatives. The systematic name of this enzyme class is threonine racemase.

Editorial summary

This brief starts where responsible research should: with the source description of “Threonine racemase” as class of enzymes. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1954, 1021—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Threonine, racemase and class can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as class of enzymes. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 18, 2025. The linked authority identifier is Q7798076. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1954 and 1021.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
