Genes

Locus	Cultural Requirements	Link Group	Type
arg-12	Uses arginine or citrulline.	IIR	B
ure-3	IIR. Between arg-12 (7 to 12%) and ace-1 (14%) (PB). Allele B1 is closely linked to translocation T(IR;II)B1 in the original strain. Consequently, ure-3 was at first assigned incorrectly to IR (78, 452). Point-mutant allele F29 shows linkage in IIR, not in IR (PB). No urease activity (452) (Fig. 10 and 24). Some revertants show altered urease thermostability, suggesting a structural role (78). For scoring methods, see ure.	IIR	B
