  1. N.d. = not detected. *These ureohydrolases are annotated as arginases, as agmatinases as well as 4-guanidino butyrases. The (+) in Table 3 for A2.1, B1, and E2 refers to an identical gene, because the gene annotation does not distinguish between arginases, agmatinases, and 4-guanidino butyrases. A classification is only possible in a few cases, in which enzymatic activity has been measured or the similarity values are very high to already biochemically well-characterized enzymes (see text for details).
