Modelling the evolution of the archaeal tryptophan synthase

Table 1 cons_clscores for trp genes

cons_Cl– values		Protein	COG #	Function
Archaea	Bacteria
2.0	2.8	TrpE	COG0147	anthranilate/para-aminobenzoate synthases comp. I
2.1	2.7	TrpG	COG0512	anthranilate/para-aminobenzoate synthases comp. II
1.8	2.3	TrpF	COG0135	phosphoribosylanthranilate isomerase
1.8	2.9	TrpC	COG0134	indole-3-glycerol phosphate synthase
1.9	3.0	TrpA	COG0159	tryptophan synthase alpha chain
1.4	3.0	TrpB1	COG0133	tryptophan synthase beta chain
0.6	-	TrpB2	COG1350	paralogue of TrpB
1.9	2.6	TrpD	COG0547	anthranilate phosphoribosyltransferase

Note: The first two columns list score values deduced from representative sets of archaeal and bacterial genomes. Columns three and four list protein names, COG numbers, and protein function. The cons_cl-scores were determined by using AMIGOS [27]. COG numbers indicate orthologous gene clusters as defined in the COG database [29].
