Acta Crystallographica Section D welcomes the submission of articles covering any aspect of structural biology, with a particular emphasis on the structures of biological macromolecules or the methods used to determine them.Reports on new structures of biological importance may address the smallest macromolecules to the largest complex molecular machines. These structures may have been determined using any structural biology technique including crystallography, NMR, cryoEM and/or other techniques. The key criterion is that such articles must present significant new insights into biological, chemical or medical sciences. The inclusion of complementary data that support the conclusions drawn from the structural studies (such as binding studies, mass spectrometry, enzyme assays, or analysis of mutants or other modified forms of biological macromolecule) is encouraged.Methods articles may include new approaches to any aspect of biological structure determination or structure analysis but will only be accepted where they focus on new methods that are demonstrated to be of general applicability and importance to structural biology. Articles describing particularly difficult problems in structural biology are also welcomed, if the analysis would provide useful insights to others facing similar problems.

晶體學(xué)報(bào)D部分歡迎提交涵蓋結(jié)構(gòu)生物學(xué)任何方面的文章，特別強(qiáng)調(diào)生物大分子的結(jié)構(gòu)或用于測(cè)定它們的方法。關(guān)于生物重要性的新結(jié)構(gòu)的報(bào)告可能會(huì)把最小的大分子提到最大的復(fù)雜分子機(jī)器上。這些結(jié)構(gòu)可使用任何結(jié)構(gòu)生物學(xué)技術(shù)（包括結(jié)晶學(xué)、核磁共振、低溫和/或其他技術(shù)）來(lái)確定。關(guān)鍵標(biāo)準(zhǔn)是，這些文章必須對(duì)生物、化學(xué)或醫(yī)學(xué)科學(xué)提出重要的新見(jiàn)解。鼓勵(lì)納入支持結(jié)構(gòu)研究得出結(jié)論的補(bǔ)充數(shù)據(jù)（如結(jié)合研究、質(zhì)譜分析、酶分析或突變物或其他生物大分子修飾形式的分析）。方法文章可能包括生物結(jié)構(gòu)測(cè)定或結(jié)構(gòu)分析的任何方面的新方法，但只有當(dāng)它們側(cè)重于證明對(duì)結(jié)構(gòu)生物學(xué)具有普遍適用性和重要性的新方法時(shí)才會(huì)被接受。如果分析能為其他面臨類似問(wèn)題的人提供有用的見(jiàn)解，那么描述結(jié)構(gòu)生物學(xué)中特別困難的問(wèn)題的文章也受到歡迎。
