Genes

Locus	Cultural Requirements	Link Group	Type
pmg	IIL. Linked to pyr-4. Right of ro-3 (4%) (29%). Centromere linked. Not linked to mtr(pmn) or to pmb in IVR (248). (Previous report of mating type linkage [862] not confirmed). Greatly reduced in general amino acid transport system II (as defined in reference 777). Reduced uptake of arginine and phenylalanine. Selected by resistance to p-fluorophenylalanine in a neutral (system I), basic (system III) double mutant on medium lacking ammonium ions, where system II would be derepressed in the wild type (248, 862, 863). A non-metabolizable substrate specific for this transport system has been found (767). Called pm g. See Transport.	IIL	B
pmn	Allelic with mtr (R. Sadler and S. Ogilvie-Villa, personal communication; A.G. De Busk, personal communication), q. v. - Called Pm-N and pm n.		B
pmb	IVR. Right of uvs-2 (8%) (S. Ogilvie-Villa, cited in reference 248; R. Sadler and S. Ogilvie-Villa, personal communication). Defective in basic L-amino acid transport (system III as defined in reference 778); reduced uptake of L-arginine, L-lysine, and L-histidine (778, 1152, 1076). Used extensively for transport studies; see reference 1150. Altered surface glycoprotein (1038). pmb mutants selected as resistant to L-canavanine (889, 1152). Allelic with bat (R. Sadler and S. Ogilvie-Villa, personal communication), which was selected in arg-12s;pyr-3 (CPS- ACT+) by ability to grow on minimal medium plus arginine, when the parental double mutant was not able to grow because of arginine uptake and feedback onto the arginine-specific carbamyl phosphate synthase (1074). Possibly allelic with basa, which was selected by the inability of the mutant his-3 to grow on histidine plus methionine (628). Probably allelic with bm-1 (linked to pyr-2, 24%), which was selected by canavanine resistance (913). Probably allelic with argR (565, 566), q.v. Called Cr-10, Pm-B, pm b, UM-535, and can-37.
