Ignore hits to items matching EC 5.3.1.16 when looking for 'other' hits
Comment: PRAI is sometimes known as trpF or as part of trpC (if fused to IGPS). In Bacteroides thetaiotaomicron, BT0528 (Q8AAD7_BACTN) has a PRAI domain (PF00697), is auxotrophic, and clusters with trp synthesis genes Similarly, annotate CCNA_03659 (A0A0H3CC53_CAUVN), SMc02767 (TRPF_RHIME), and Ga0059261_0237 (A0A1L6JC25_9SPHN). Some bacteria have a bifunctional phosphoribosylanthranilate isomerase (EC 5.3.1.24) and isomerase in histidine biosynthesis (hisA, EC 5.3.1.16), for instance P16250. (In both reactions a N-modified-1-amino-ribofuranose-5-phosphate rearranges to a linear N-modified-1-amino-ribulose-5-phosphate.) So hits to hisA are ignored.
