酚氧化酶之意是能利用过氧化氢或分子氧氧化含有酚基的有机化合物的酶。这类酶的例子是过氧化物酶和氧化酶。
早期已经发现,从染色的织物沥滤的有色物质能够用酚氧化酶来漂白。用过氧化物酶或氧化酶来抑制这种方式的染料转移叙述于WO91/05839中。
某些可氧化的物质,例如金属离子和诸如7-羟基香豆素、香兰素和对羟基苯磺酸盐之类的酚化合物,是作为能够增强酶的漂白反应的促进剂或增强剂来叙述的(参阅,例如WO92/18683;WO92/18687;Kato M和Shimizu S,植物细胞生理学(Plant Cell Physio1.)1985,26(7),PP.1291-1301(特别参阅表1))。WO94/12621公开了其它类型的增强剂,例如吩噻嗪和吩噁嗪。
本发明的目的是提供一组新的可有效增强酚氧化酶的增强剂。
发明概述
现已惊人地发现了一组新的能够极好地起着酚氧化酶增强剂作用的有机化学物质。

附图简述
本发明用图1进行进一步的说明。图1显示于35℃下逐渐加入在磷酸盐/硼酸盐缓冲液(pH10)中的酸性蓝45的漂白作用,按实施例8中所述进行实验。(I):只加入染料;(II):在漆酶存在下加入染料;(III):在漆酶和乙酰丁香酮存在下加入染料。
本发明详述

着色剂和染料有天然的和合成的化合物,其类别广泛。下面的叙述以及染料/着色剂实例无论如何无意对要求保护的本发明范围进行限制。
可用本发明方法漂白的合成纺织品染料一般是偶氮化合物(具有一个或几个偶氮或二氮亚烯基),以酸性红151、直接蓝1、直接棕44和橙II为例;或者是蒽醌化合物,以酸性蓝45为例:直接蓝1直接棕44橙II酸性蓝45其它的结构可沿此而出现,以活性蓝19的化学式为例:活性蓝19
某些染料还带有能偶合于织物表面的基团(活性染料);某些染料与金属离子配合。这些改性通常不会影响本发明的应用性。

下面以实施例进一步说明本发明,但它们无论如何不欲限制要求保护的本发明范围。实施例1用大豆过氧化物酶在有和无乙酰丁香酮存在下漂白直接蓝1
用阴离子和阳离子色谱纯化得自Mead公司(Dayton,Ohio)的粗品大豆过氧化物酶(SBP),接着进行凝胶过滤至在SDS-PAGE上有Rz值(A404nm/A280nm)为2.2的单一蛋白质。
将125ml粗品SBP调至pH7,稀释至2.3mS,并通过0.8μ过滤器过滤。将样品加入300ml用20mM磷酸盐缓冲液(pH7.0)平衡的DEAE柱,并用1M NaCl在相同缓冲液中成线性梯度的溶液洗脱过氧化物酶。收集有过氧化物酶活性的级分。
浓缩从阴离子交换色谱柱洗脱的收集级分(190ml),超滤洗涤(GR 61 PP膜,Dow化学公司(Denmark)提供)。将pH调至5.3,样品中离子强度调至2.3mS,然后加到事先用50mM醋酸盐缓冲液(pH5.3)平衡的200ml S-Sepharose柱中。浓缩有过氧化物酶活性的洗脱液并超滤洗涤至终体积约为10ml。
将从阳离子交换色谱柱洗脱的5ml浓缩样品加入用0.1M醋酸盐缓冲液(pH6.1)平衡的90cm Sephacryl S-200柱,并用该缓冲液洗脱。收集在SDS-PAGE上只有一个谱带的有过氧化物酶活性的级分。
用本发明的增强剂测定纯化的SBP对直接蓝1(DB1)的漂白率。所用的条件如下:

将各试剂在一恒温30℃的比色杯中混合,加入过氧化氢时漂白开始。用610nm波长(它是DB1吸收峰波长)以分光光度测定法检测漂白情况。漂白继续4分钟,计算吸光度的降低(100×(A610nm,开始-A610nm,4分钟/A610nm,开始%)。
用水代替过氧化氢测定A610nm,开始。表1以SBP漂白直接蓝1(DB1)4分钟

从表1的结果可见,加入本发明的增强剂比不加增强剂的实验得到的染料漂白要快得多。实施例2 用灰盖鬼伞过氧化物酶在有和无增强剂存在下漂白直接蓝1
所用的灰盖鬼伞过氧化物酶(Cip)如WO9412621中所述方法得到。
Cip是在0.15g/l的Triton X-405溶液中稀释的。
纯化的Cip对直接蓝1(DB1)的漂白率测定所用的条件如下:
最终浓度
200μl 50mM Britton-Robinson缓冲液* 10mM
200μl DB1~3.0绝对单位(610nm) 0.6(A610nm)
200μl 0.40mg/l Cip(pH8.5) 0.08mg/l(pH8.5)

200μl 100μM H2O2 20μM*(50mM醋酸,50mM磷酸,50mM硼酸,用NaOH将pH调至欲试值)
在恒温30℃的比色杯中混合各试剂,在加入过氧化氢时漂白开始。用分光光度测定法在610nm波长(DBl吸收峰波长)检测漂白情况。漂白继续1分钟,并测定吸光度的初始降低,-ΔmAbs/分钟。表2 使用CiP对直接蓝1的初始漂白

从表2的结果可看出加入本发明的增强剂比没有增强剂的实验所得到的染料漂白要快得多。甚至是在pH10.5,用本发明的增强剂也得到了显著的漂白效果,而在不加增强剂时,全然见不到漂白作用。实施例3 用灰盖鬼伞过氧化物酶和增强剂漂白芝加哥天蓝6B(CSB)

从上述结果可见,在pH7左右得到了最佳漂白,但此体系在pH8也显示了有效的漂白作用。实施例7 用Trametes villosa漆酶在有和无增强剂存在下的直接蓝1的漂白
从Trametes villosa制取漆酶:用助滤剂过滤800ml Trametesvillosa(CBS 678.70)培养液,得到清澈滤液,滤液用6-8KDa间隔(cut-off)的膜超滤浓缩并洗涤。将1ml浓缩的制剂样品加到用0.1M磷酸盐缓冲液(pH7)平衡的Q-Sepharose HP柱(Pharmacia,SWeden)上,用0.25M左右的NaCl平坦梯度洗脱漆酶。收集10次实验的有漆酶活性的级份并超滤浓缩至活性为500LACU/ml。
所使用的条件如下:
最终浓度
400μl 50mM Britton-Robinson缓冲液*
(pH分别为5.5和7.0) 20mM
200μl DB1~3.0绝对单位(610nm) 0.6(A610nm)
200μl 50μM增强剂 10μM
200μl酶稀释液*(50mM醋酸,50mM磷酸,50mM硼酸;用NaOH将pH调至欲试值)
在恒温30℃的1ml比色杯中将试剂混合,加入酶时,漂白开始。
用分光光度法于610nm(DB1吸收峰波长)检测漂白,5秒钟后,漂白继续进行4分钟。
从下面所列的结果来看,与不加增强剂的实验相比,加入本发明增强剂得到的染料漂白要快得多。所给酶剂量是在最后的培养混合物中。
用Trametes villosa漆酶(按上述方法制得)于pH5.5(1.6mg/l)和pH7.0(16mg/l)漂白直接蓝1:
DB1漂白4分钟
(-ΔmAbs/分钟)
增强剂 pH5.5 pH7.0
无增强剂 0 0
乙酰丁香酮 447 242
丁香醛 438 112实施例8 用灰盖鬼伞漆酶在有和无增强剂存在下漂白逐渐加入的酸性蓝45
理想的用于洗衣的染料转移抑制体系应当在染色织物因洗涤剂、温度和机械搅拌产生的联合作用将染料释放到洗涤液中的真正洗涤中进行试验。
然而,为了模拟这一过程,用一以电磁搅拌的烧杯作为反应容器,并从储备溶液(用Metrohm 72.5计量器)逐渐加入染料。用装有光学纤维浸入式探测器的蔡司多通道分光计(MCS)对溶液以分光光度测定法进行监测。
乙酰丁香酮储备溶液是在合适的水/乙醇混合物中制备的。酸性蓝45蒽醌染料储备溶液是在水中制备的。
从10升灰盖鬼伞(IFO 30116)的发酵液中如实施例4所述回收漆酶。
实验所用条件如下:温度:35℃培养在和pH:50mM/50mM磷酸盐/硼酸盐缓冲液,pH10乙酰丁香酮(若使用的话):10μM漆酶:10mg/l加染料程序:以大约0.34abs/40分钟的速率(指酸性蓝45在最大吸收波长590nm的吸光度)作线性添加。
图1所示为漂白试验结果。所用符号含义如下:(I)-只加入染料;(II)-在漆酶存在下加染料;(III)-在漆酶和乙酰丁香酮存在下加染料。
从图1可见,漂白作用由于乙酰丁香酮而增强。实施例9 用灰盖鬼伞漆酶抑制染料转移
