^aIn the standard single-letter symbols.

^bIndicated by poor growth similar to that of strain BK after 42 h of growth on GNGlnTrp medium at 37°C.

^cResulting in a glnL consisting of codons 1 to 120, followed by an insertion of CAT encoding histidine, followed by codons 119 to 349.

^dND, not determined.
