Source-derived summary

In enzymology, a 1D-1-guanidino-3-amino-1,3-dideoxy-scyllo-inositol transaminase (EC 2.6.1.56) is an enzyme that catalyzes the chemical reaction

1D-1-guanidino-3-amino-1,3-dideoxy-scyllo-inositol + pyruvate

⇌

{\displaystyle \rightleftharpoons }

1D-1-guanidino-1-deoxy-3-dehydro-scyllo-inositol + L-alanine

Thus, the two substrates of this enzyme are 1D-1-guanidino-3-amino-1,3-dideoxy-scyllo-inositol and pyruvate, whereas its two products are 1D-1-guanidino-1-deoxy-3-dehydro-scyllo-inositol and L-alanine.

This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is 1D-1-guanidino-3-amino-1,3-dideoxy-scyllo-inositol:pyruvate aminotransferase. Other names in common use include guanidinoaminodideoxy-scyllo-inositol-pyruvate aminotransferase, and L-alanine-N-amidino-3-(or 5-)keto-scyllo-inosamine transaminase.

Editorial summary

The public source identifies “1D-1-guanidino-3-amino-1,3-dideoxy-scyllo-inositol transaminase” as class of enzymes. This brief keeps that definition visible, then builds a research path around 1D-1-guanidino-3-amino-1, 3-dideoxy-scyllo-inositol and transaminase.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1971, 1969—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with 1D-1-guanidino-3-amino-1, 3-dideoxy-scyllo-inositol and transaminase providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “1D-1-guanidino-3-amino-1,3-dideoxy-scyllo-inositol transaminase”, the useful work is to connect “class of enzymes” to the records capable of establishing context and consequence.

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 Aug 26, 2023. The linked authority identifier is Q4595877. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1971 and 1969.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
