Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the ‘correct annotation’ for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

This protein is involved in step 1 of the subpathway that synthesizes L-homocysteine from S-adenosyl-L-homocysteine.
Proteins known to be involved in this subpathway in this organism are:
  1. Adenosylhomocysteinase (AHCYL1), Adenosylhomocysteinase (AHCYL1), Adenosylhomocysteinase, Adenosylhomocysteinase (AHCY), Adenosylhomocysteinase, Adenosylhomocysteinase (AHCY), Adenosylhomocysteinase (FGFR2-AHCYL1), Adenosylhomocysteinase 3 (AHCYL2)
This subpathway is part of the pathway L-homocysteine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-homocysteine from S-adenosyl-L-homocysteine, the pathway L-homocysteine biosynthesis and in Amino-acid biosynthesis.
