uc-4	VR. Between inl (12%) and his-6 (11%) (126). Not in I as reported in references 1139 and 1141 on the basis of one ascus in eight recombinant with mt. Thymidine salvage pathway defect (Fig. 23). Unable to use thymidine, thymine, 5-hydroxymethyluracil, 5-formyluracil, or uracil to support pyr-1, even in the presence of a uridine primer (1141). Deficient in phosphoribosyl transferase (127). The uc-4 single mutant converts 50% of the supplied uridine to uracil and excretes it into the medium (1141). Resistant to 5-fluorouracil (126).	VR	B
