Glu124 (in α1) makes a bidentate salt bridge to Arg97 (in α1 and conditionally essential at 18°) and accepts a hydrogen bond from the main-chain amide of Phe108 (in the loop). Arg97, in turn, donates hydrogen bonds to Gln100 and the main-chain carbonyl of Pro106. It was shown previously that replacing Gln110 with arginine results in cold-sensitive and temperature-sensitive growth defects (Tan et al. 2003).","tracks":[{"project":"2_test","denotations":[{"id":"25911228-12697831-43354280","span":{"begin":562,"end":566},"obj":"12697831"}],"attributes":[{"subj":"25911228-12697831-43354280","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#e9ec93","default":true}]}]}}
