Biology

sucCD operon, SucD = alpha subunit, 89% identical to E. coli SucD PMID:10671455.
SCS reaction with purified subunits PMID:10671455.

NDP-kinase-like transphosphorylation PMID:10671455.

Annotation decisions

GO:0004775 (IBA, IEA, IDA), GO:0004776 (IBA, IEA, EXP), GO:0006099 (IBA, IEA), GO:0009361 (IBA),
GO:0042709 (IEA, IDA): ACCEPT.
GO:0004550 NDP kinase (IDA): MARK_AS_OVER_ANNOTATED (as sucC).
GO:0009142 NTP biosynthesis (IDA): KEEP_AS_NON_CORE (as sucC).
GO:0003824 (IEA): TOO_GENERAL.
GO:0042709 is kept beside GO:0009361 (its is_a descendant) because the enzyme is equally
GDP-forming; TOO_GENERAL would imply the ADP-forming complex is the whole story.
Action counts: ACCEPT 11, MARK_AS_OVER_ANNOTATED 1, KEEP_AS_NON_CORE 1, TOO_GENERAL 1.

PseudoCAP IBA-seed assessment

PTN node	node term	n_seeds	leaf IBAs	seed annotation (term, evidence, PMID)	verdict	rationale	other seeds	IBD stands without this seed?
PTN000122012	GO:0004775 succinate-CoA ligase (ADP-forming) activity	6	185 (127 taxa)	GO:0004775, IDA, PMID:10671455 (PseudoCAP)	SOUND	Full text: purified SucC+SucD run the SCS reaction in both directions and make ATP from succinyl-CoA, Pi and ADP.	E. coli SucD P0AGE9, human SUCLG1 P53597, rat Suclg1 (RGD:619821), tomato SCS-alpha1/alpha2 Q8GTQ9/Q6DQL1	Yes; five other characterised alpha subunits, and the term suits an alpha-subunit clade shared by ADP- and GDP-forming enzymes

sucD does not share a PTN node with sucC: sucC's seed node is PTN000212531 (beta-subunit family).
No node defect to record. No PSEUDOCAP or GO_CENTRAL defect on sucD.
