Remark 650 | HELIX RESIDUES ARE INCLUDED AT THE BEGINNING OF HELICES IF THEY PARTICIPATE IN HYDROGEN BONDING AND ...HELIX RESIDUES ARE INCLUDED AT THE BEGINNING OF HELICES IF THEY PARTICIPATE IN HYDROGEN BONDING AND ARE "PARTIALLY" HELICAL, EVEN IF THE ENTIRE RESIDUE DOES NOT FIT HELICAL CRITERIA. | ||||||
Remark 700 | SHEET PROFILIN IS DESCRIBED IN JRNL REFERENCE AS HAVING A SIX-MEMBERED BETA-SHEET WHICH SHARES A ...SHEET PROFILIN IS DESCRIBED IN JRNL REFERENCE AS HAVING A SIX-MEMBERED BETA-SHEET WHICH SHARES A STRAND WITH A SECOND TWO-MEMBERED SHEET. TO CONFORM WITH PROTEIN DATA BANK GUIDELINES, THESE SHEETS ARE COMBINED INTO A SINGLE SEVEN-MEMBERED SHEET (SP1) IN THIS ENTRY. STRAND NUMBERING ALSO DIFFERS FROM THE JRNL REFERENCE. SECONDARY STRUCTURE ASSIGNMENTS FOR BETA-ACTIN ARE SIMILAR TO THOSE USED FOR ALPHA-ACTIN (PROTEIN DATA BANK ENTRY 1ATN) WITH MINOR CHANGES. HOWEVER, THE NOMENCLATURE USED HEREIN DIFFERS FROM THAT USED IN THE ABOVE ENTRY. ALSO, STRAND A4B DESCRIBED IN THAT ENTRY IS NOT INCLUDED HERE BECAUSE THE "ALTERNATIVE" STRAND TO ONE IN STRAND A4A (CORRESPONDING TO SA4 IN THIS ENTRY) IS ONLY TWO RESIDUES IN LENGTH. IN CONTRAST, SHEET SA3 IS INCLUDED BECAUSE IT CONTAINS TWO STRANDS AND A WELL-DEFINED TYPE II TURN, EVEN THOUGH THE TWO STRANDS CONTAIN ONLY TWO RESIDUES EACH. RESIDUE P 31 IS A BETA-BULGE. RESIDUE P 73 IS A BETA-BULGE, REDIRECTING STRAND 6. |
