-
F27A, R71Q, TPT1(1-220) and TPT1(1-210) cells failed to grow at 37°C on yeast medium/peptone/dextrose agar, R71Q and TPT1(1-210) strains grew slower than wild-type TPT1
18 - 37
-
growth of mutants K16A, K69A, H90A, S91A, H117A, T119A, H142A, R158A and R138K on yeast medium/peptone/dextrose agar, colony sizes were similar to that of wild-type TPT1 cells

-
growth of mutants K16A, Y38A, K69A, F72A, H90A, S91A, H117A, T119A, H142A, R158A, TPT1(1-220) and TPT1(1-210) on 5-fluoroorotic acid agar medium

ApeTpt1 caps the pDNA substrate with high yield (94-100%) at temperatures ranging from 37°C to 65°C and with progressively lower yields at 75°C (68%), 85°C (32%), and 95°C (21%)
