REMARK 5
REMARK 5 1CHB ASYMMETRIC UNIT CONTAINS ONE B PENTAMER COMPLEXED WITH
REMARK 5 1CHB FIVE MOLECULES OF THE PENTASACCHARIDE WHICH FORMS THE
REMARK 5 1CHB EXTRA-CELLULAR PORTION OF GANGLIOSIDE GM1 (THE
REMARK 5 RECEPTOR 1CHB FOR THE CHOLERA TOXIN). 1CHB
REMARK 6
REMARK 6 1CHB THE FIVE IDENTICAL B SUBUNITS ARE LABELLED AS CHAINS
REMARK 6 D, E, 1CHB F, G, AND H CORRESPONDING TO CHAIN IDENTIFIERS

REMARK 7 1CHB INITIAL MET RESIDUE OF EACH B SUBUNIT (NOT PRESENT IN
REMARK 7 1CHB NATURALLY OCCURRING TOXIN) IS OMITED FROM MODEL DUE TO
REMARK 7 LACK 1CHB OF ELECTRON DENSITY. 1CHB SACCHARIDE MODEL IS
REMARK 7 INCOMPLETE IN FOUR OF THE FIVE COPIES. 1CHB ELECTRON
REMARK 7 DENSITY IS PRESENT IN ALL CASES, BUT IS NOT 1CHB
