Table 1 Definition of EC numbers in NC-IUBMB

From: Consensus and conflict cards for metabolic pathway databases

EC number

Enzyme name

Reaction as defined by NC-IUBMB

2.7.4.4

Nucleoside-phosphate kinase

ATP + nucleoside phosphate =

ADP + nucleoside diphosphate

2.7.4.14

UMP/CMP kinase

(1) ATP + (d)CMP = ADP + (d)CDP

(2) ATP + UMP = ADP + UDP

2.7.4.22

UMP kinase

ATP + UMP = ADP + UDP

  1. The enzyme name and reaction(s) linked to the EC numbers of Figure 2 by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB). The information of NC-IUBMB is available in a C2Card for each EC number that is part of the overview (see Figure 1). Note that the EC number 2.7.4.22 is unlikely to be correct in this case as NC-IUBMB indicates that this particular enzyme is the prokaryotic variant of the enzyme linked to EC number 2.7.4.4.
